1.0 Introduction

This tutorial is a simple introductory tutorial that helps you become familiar with the basic modelling and data interpretation features of RocSlope2.

An essential part of your rock slope analysis toolkit, RocSlope2 allows you to quickly identify and analyze the critical mode of structural failure. RocSlope2 is an easy-to-use software where users can perform entire kinematic analysis of wedge, planar and toppling analysis in one day to obtain Factors of Safety and Probability of Failures determined through limit-equilibrium analyses. RocSlope2's direct integration with the Rocscience Dips software enables a smooth extension from kinematic analysis in Dips to a full equilibrium analysis in RocSlope2.

Learn more about RocSlope2's capabilities in the official RocSlope2 Product Announcement.

3.0 Project Settings

The Project Settings dialog allows you to configure the main analysis parameters for your model, such as Analysis Method, Analysis Type and Units. To open the dialog:

  1. Select Home > Analysis > Project Settings Project Settings Icon on the toolbar.
Project Settings Dialog
RocSlope2 Project Settings dialog

3.1 Analysis Method

There are three main analysis methods in RocSlope2: Wedge, Planar and Toppling. All analysis methods are enabled by default and can be enabled/disabled depending on the desired failure mode analysis to be performed.

In this tutorial we will perform analysis for all three failure modes of wedge, planar and toppling.

  • Wedge method is used to evaluate the stability of surface wedges in rock slopes defined by two (or three) intersecting discontinuity planes, the slope surface, and an optional tension crack.
  • Planar method is used to assess the stability of planar sliding blocks/wedges in rock slopes while sliding occurs on a plane that strikes approximately parallel to the strike of the slope face.
  • Toppling method is used to perform stability analysis of toppling block which is based on the popular limit equilibrium block toppling method of Goodman and Bray first published in 1976 in the paper, Toppling of Rock Slopes, and the block flexure toppling method of Amini, Majdi and Veshadi published in 2012 in the paper, Stability Analysis of Rock Slopes Against Block-Flexure Toppling Failure.

3.2 Analysis Type

There are two main analysis types in RocSlope2: Deterministic and Probabilistic. Deterministic is the default analysis type.

  • A Deterministic analysis assumes that all input parameters are exactly known. RocSlope2 computes the Factor of Safety (FS) for a single set of input data for enabled analysis methods of wedge, planar and/or toppling failure. This tutorial demonstrates a Deterministic analysis.
  • For a Probabilistic analysis, statistical input data can be entered to account for uncertainty in input data such as slope geometry, joint orientation, strength values, etc. The result is a distribution of Factors of Safety, from which a Probability of Failure is calculated. Probabilistic analysis is demonstrated in Tutorial 05 - Sensitivity & Probabilistic Analysis in RocSlope2.

3.3 Units

The Units setting determines the length and force units used in the analysis. In this tutorial we are using metric kPa units.

  1. Ensure that the Units are Metric, stress as kPa in the Units tab in Project Settings (the default setting).
Whenever the stress Units are changed a Unit Conversion dialog pops up asking if you want the existing property values to be converted into the new units. Select "Yes" to convert all existing property values into the selected units.

3.4 Project Summary

  1. Select Home > Information > Project Summary Project Summary Icon toolbar.
  2. Enter RocSlope2 Quick Start Tutorial as the Project Title.

4.0 Input Data

Slope Geometry, Slope Properties, Joint Orientation and Joint Properties are the four main input data where data is entered through each corresponding menu.

4.1 Slope Geometry

Slope Geometry is the input data dialog for entering slope geometry data in RocSlope2.

  1. Select Home > Slope > Geometry Slope Geometry Icon
    Deterministic Slope Geometry Input Data Dialog
    Deterministic Slope Geometry Input Data Dialog
  2. Examine the Slope input data. The Slope face Orientation (Dip, Dip Direction), Height, Upper face Orientation (Dip, Direction) are required for wedge and planar analysis. Overall base inclination (Dip, Dip Direction) is also required for toppling analysis. All other Slope Geometry input data is optional.
  3. Change the Slope Geometry input data using the following data:
    Slope Face Dip (º) 70
    Slope Face Dip Direction (º) 45
    Height (m) 20

    Slope Face Length (m)

    50

    Upper Face Dip (º)

    5
    Upper Face Dip Direction (º) 45
    Overall Base Inclination/Dip (º) 42
  4. Enable Use Default Bench Width by click on the checkbox next to it.
    Slope Geometry Input
  5. Press OK to close the dialog.

4.2 Slope Properties

Slope Properties is the input data dialog for entering the data for Rock Unit Weight, Water Parameters and Rock Material Strength if the Block Flexure Toppling is enabled.

  1. Select Home > Slope > Properties Slope Properties Icon
    Deterministic Slope Properties Input Data dialog
    Deterministic Slope Properties Input Data dialog
  2. Examine the Slope Properties input data. Rock Unit Weight is required while all other Slope Properties input data is optional.
  3. Leave the Slope Properties data as is since we will proceed with default data and click OK.

4.3 Joint Orientations

Joint Orientations is the input data dialog to define the Joint Orientations (Dip, Direction), assign Joint Property to each joint, define Joint Spacing for toppling analysis, and set Lateral Limits for sliding and toppling joints if desired.

  1. Select Home > Joints > Orientations Joint Orientation Icon
  2. Examine the Joint Orientation input data.
  3. Change the Joint Spacing under Toppling Analysis Settings to 2.
  4. Set Base Joint Property to Joint Property 2.
  5. Edit the Joint Orientation input data using the following data:
    Joint No Dip (°) Dip Direction (°) Joint Property
    1 70 14 Joint Property 1

    2

    65 220 Joint Property 1

    3

    74 145 Joint Property 1

    4

    45 52 Joint Property 1

    Deterministic Joint Orientation Input Data dialog
    Deterministic Joint Orientation Input Data dialog
  6. Ensure the Sliding and Toppling lateral limits are as follows:
    • Sliding Joint Lateral Limits = 20º
    • Toppling Joint Lateral Limits = 30º
  7. Click OK to close the dialog.
In practice, it has been observed that Planar Sliding and Toppling tend to occur when the dip direction of joint planes is within a certain angular range of the slope dip direction. Lateral Limits define the lateral extends of the critical zone with respect to the Slope Dip Direction and typically a range of plus/minus 20 or 30 degrees is considered, and poles outside of this range represent a low risk.
All joints defined in RocSlope2 are added under Joint Set 1 by default. To define another Joint Set and add joints under this set, enable Use Separate Joint Sets checkbox to activate Joint Set 2. Basal Joint Set is also automatically activated when the Basal Joint is select in Project Settings > Wedge Settings.

4.4 Joint Properties

Joint Properties is the input data dialog to define the Joint Strength (Strength Type and Parameters) and Water Parameters (Pressure Distribution Model and Data).

  1. Select Home > Joints > Properties Joint Properties Icon
  2. Ensure the Joint Property 1 data as follows:
    • Cohesion (kPa) = 0
    • Phi (º) = 35
    • Waviness (º) = 0
      Deterministic Joint Properties Input Data dialog – Joint Property 1
      Deterministic Joint Properties Input Data dialog – Joint Property 1
  3. Select Joint Property 2 and enter the following data:
    • Cohesion (kPa) = 5
    • Phi (º) = 32
    • Waviness (º) = 2
      Deterministic Joint Properties Input Data dialog – Joint Property 2
      Deterministic Joint Properties Input Data dialog – Joint Property 2

      The Waviness angle accounts for the waviness (undulations) of a joint surface, observed over distances on the order of 1m to 10m. It has the effect of increasing the shear strength of the joint. For more help on this input property, see Joint Waviness Angle.
  4. Click OK to close the dialog.

Notice that the Factor of Safety (FS) for Wedge, Planar and Toppling Analyses are computed instantly. You should see the Wedge Analysis with a Factor of Safety of 0.7, Planar Analysis with a Factor of Safety of 0.7 and Toppling Analysis with a Factor of Safety of 0.722.

14.0 Additional Exercise

14.1 Scale Block

The Scale Block option allows you to limit or scale the size of blocks in the Wedge or Planar analysis models according to Joint Trace Lengths and/or Maximum Persistence (Wedge analysis), Failure Plane (Planar analysis), Wedge Volume or Weight (both).

Let's start by scaling Block ID=3 wedge by Trace Length.

  1. First select Block ID=3 by double clicking it in the Results Grid.
  2. Then to open the Scale Block dialog, select Home > Analysis > Scale Block Scale Block
  3. Under Trace Lengths, select the Joint 1 check box and enter Scaling Values = 7 in the corresponding box.
    Note that the current value of the parameter is listed under Current Values.
  4. Click Apply.
Scale Block dialog
Scale Block dialog

Because we entered a Trace Length of 7 m for Joint 1, which is smaller than the Current Value of 10.47 meters, the wedge size has been reduced accordingly. Note that the Trace Length may occur on EITHER the Slope Face or the Upper Face. The larger value is always used.

Note the following:

  • The wedge Volume has been reduced to 122.64 m3.
  • The wedge Weight has been reduced to 3188.69 kN.
  • The wedge Factor of Safety is 0.7.

Double click on any block in the Results Grid while the Scale Block dialog is open to select the block and examine its scaled values. Notice that the scaling value we entered is applied all the blocks listed in Results Grid for Wedge Analysis.

You can similarly scale the wedge size by Maximum Persistence in the Scale Block dialog. The persistence refers to the maximum dimension between any two points, as measured on the wedge failure surfaces (Joint 1 and Joint 2).

Now, let's scale Block ID = 3 wedge by Volume.

  1. Select Home > Analysis > Scale Block scale icon to re-open the Scale Block dialog.
  2. Under Wedge Data, select the Volume check box and enter Scaling Values =100 in the corresponding box.
    Note that the current value of the parameter is listed under Current Values.
  3. Click Apply.
Scale Block dialog
Scale Block dialog

The wedge size is again reduced.

Note the following:

  • The wedge Volume has been reduced to 100 m3.
  • The wedge Weight has been reduced to 2600 kN.
  • The wedge Factor of Safety is 0.7.

Double click on any block in the Results Grid while Scale Block dialog is open to select the block and examine its newly scaled values.

The general rule here is: "When multiple scaling parameters are defined, the parameter that results in the smallest wedge controls the wedge size."

For a Probabilistic Analysis, multiple scaling parameters can be useful if the wedge plane orientations are random variables, because different scaling parameters may be applied to different wedges. However, for any individual wedge generated by a Probabilistic, only the scaling parameter which gives the smallest wedge will be applied.

The Scale Block option cannot be used in conjunction with the Persistence Analysis option. If the Persistence Analysis option is in use, then the Scale Block option will NOT be available, and vice-versa.

To conclude:

  1. Select Home > Analysis > Scale Block Scale Block one more time to re-open the Scale Block dialog.
  2. Click on Maximize to reset wedge scaling.
  3. Click OK.

Repeat the scaling exercise for Planar Analysis.

This concludes the tutorial. You are now ready to proceed to the next tutorial, Tutorial 2 – Importing a Dips File.
