Discover how to use the new Print to Scale feature in Slide 5.0
The latest update to Slide 5.0 brings a number of improvements related to printing functionality, giving the user greater control over printed output. Users have the option of printing the model exactly as shown on screen, or to a specific scale. This article demonstrates the use of the new Print to Scale feature. (Slide 5.029, 04/07)

Movie: Using Optimization to search for the critical surface
This tutorial demonstrates how to use the Optimize Surface Option in Slide 5.0. This option allows users to search for critical slip surfaces. As a starting point, it can employ a user-defined surface, or surfaces generated by a Block Search or Path Search. (Slide 5.013, 07/04)

Movie: The B-Bar Method for Calculating Excess Pore Pressure
By popular demand, an important new feature has been added to the latest Slide upgrade - the calculation of Excess Pore Pressure due to undrained loading, using the so-called "B-bar" method. This feature allows you to account for short-term (transient) changes in pore pressure due to rapidly applied loading conditions. (Slide 5.010, 04/04)

Movie: Rapid Drawdown Analysis Using the B-Bar Method
The concept of excess pore pressure using the B-bar method can also be applied to unloading scenarios. If a load is removed quickly from a low permeability material, a "negative excess pore pressure" can be induced. This can be used to simulate the pore pressure changes due to rapid drawdown of ponded water in earth dams. (Slide 5.010, 04/04)

Speeding up Slope Stability Calculations involving Generalized Hoek-Brown Materials
The conversion of principal stresses to shear-normal stresses is computationally intensive. This considerably slows down slope stability analysis involving Generalized Hoek-Brown materials. Fortunately, in Slide, it is possible to significantly improve the computational speed of such analyses through combined use of the program's Shear/Normal strength function and the free Rocscience program RocLab. This program allows users to easily determine Hoek-Brown and Mohr-Coulomb strength parameters of rockmasses and intact rock samples.
The procedure for speeding rock slope stability calculations is simple. It involves generating a discrete number of points from the Generalized Hoek-Brown criterion, converting those principal stress values to shear/normal stresses and importing them into Slide. The program then uses these discrete shear/normal stress points to calculate failure surface strengths. It interpolates for strength values that lie in-between the imported points. For more details, click here. (Slide 5.03, 06/03)

Movie: Sensitivity
This movie demonstrates how to perform a sensitivity analysis in Slide. It takes an existing model and examines the sensitivity of the factor of safety to changes in cohesion, friction angle and unit weight of the material. The movie uses a simple model with one material (tutorial1, from the Examples folder), but it also explains what additional steps would be required if the model had multiple types of materials.

Movie: Back Analysis
Given a required factor of safety, Slide will now compute the reinforcement load to achieve that factor of safety for all surfaces analyzed. Whether you are required to design for a particular factor of safety or you would simply like a good starting point for your support design, you will find Slide's new back analysis feature saves you lots of time.

Movie: Using Favourite Text and Dimensioning
As you will see in the movie, you can fully annotate a model with just a few clicks of the mouse. After you have some experience using the tools, it will take so little time you won't consider annotation a chore. (Slide 5.00, 03/03)
The movie demonstrates the following:
Adding Horizontal and Vertical Dimensions
Formatting Dimensions
Using "Favourite Text" to automatically add material names
Using "Favourite Text" to automatically add coordinates
Setting various display options to achieve high quality printed output.
Possible uses for these features:
Adding material names to your model with a few clicks will eliminate much of the
typing you were doing to annotate your models. This also makes updating models
less error-prone, as the "Favourite Text" will automatically change if you change
the name of your materials, or import the text boxes into another model.
When creating a report or journal article, it is extremely useful to include an image
that fully describes the geometry in your model. This would allow someone who
is reading the report to reproduce the model, in case they do not have an
electronic copy of the model (i.e. the input file) or they use a different software
package.
This hasn't been done much in the past, since it was extremely labour-intensive, but with these tools you will be able to add this to your reports in almost no time.

Groundwater Analysis Using Slide
In this article we introduce the new groundwater/seepage analysis module, which was built into version 5.0 of Slide. The groundwater module uses a finite element formulation for modelling saturated and unsaturated steady-state flow. The distinctive feature of this new module is that it performs groundwater analysis on the same model used for slope stability analysis. The pore water pressures calculated from the new module can be automatically included in analyses by the slope stability engine in Slide. This means that with Slide, a model needs to be built only once; it is directly used for both groundwater and slope stability analysis.
Although the Slide groundwater module is geared towards the calculation of pore pressures for slope stability problems, it is not restricted to geometry configurations related to slopes only. It is a completely self-contained groundwater analysis program that can be used outside slope stability analysis. For more details, click here. (Slide 4.002, 04/02)
