RSData

The lack of data input on soil and rock mass properties can be a major obstacle when you’re running your geotechnical analyses. RSData helps to remedy this situation by providing analysis tools and data to help you determine rock and soil material properties.

RSData is a versatile toolkit for the analysis of rock and soil strength data, and the determination of strength envelopes and other physical parameters. RSData includes RocProp, a database of intact rock properties that runs as a standalone application.

Determine the parameters of linear and non-linear strength envelopes for rock and soil, based on the analysis of triaxial or direct shear strength data. Utilize four of the most widely used strength models in geotechnical engineering - Generalized Hoek-Brown, Mohr-Coulomb, Barton-Bandis, and Power Curve.

Failure envelopes are plotted in both shear-normal and principal stress space. Shear-normal stress envelopes generated can be applied to problems such as limit equilibrium analysis of slope stability, while the principal stress envelopes can be used for modeling the behaviour of underground excavations. RSData is a highly interactive program that allows users to easily test different strength parameters and observe how they impact a failure envelope, giving users a better understanding of material strength.

The material strength properties determined can be used as input for numerical analysis programs such as RS2 and Slide2.

RSData will be available commercially from December 2020.

What’s New in RSData

RSData offers a number of new features, including:

  • Newly redesigned User Interface
  • Stress Path Graphs tab: Software now includes all data stress paths and allows users to study deformation behaviour of material models
  • Customizable graphs that allow users to modify titles, value ranges, colours, selected data sets, and more
  • Animation feature for viewing nonlinear behaviour of materials and hardening/softening behaviour
  • Test Simulation feature with typical laboratory test configurations and a general loading option
  • Enhanced Properties Panel added that allows users to adjust material models, graphs, test specification and more all from main view

Strength Criteria

In RSData, you can choose to work with one of the following strength criteria:

  • Generalized Hoek-Brown
  • Mohr-Coulomb
  • Barton-Bandis
  • Power Curve

Below is a summary of the range of applicability for each strength criterion.

  • Generalized Hoek-Brown: Rock, Triaxial Data
  • Mohr-Coulomb: Rock, Soil, Joints, Triaxial Data, Direct Shear Data
  • Barton-Bandis: Joints, Direct Shear Data
  • Power Curve: Rock, Soil, Joints, Triaxial Data, Direct Shear Data

Analysis of Test Data

One of the major features of RSData is the ability to input strength test data from triaxial or direct shear tests to determine the "best fit" strength envelope and the associated strength parameters (e.g. cohesion and friction angle) for a rock or soil material. The test data can be obtained from lab tests of intact samples, or field data from in-situ rock mass tests.

Obtaining values of strength parameters from actual test data is always recommended, if possible. It should be emphasized that numerous test results are not always necessary, and good results can be obtained from a relatively small number of data points (e.g. 6 or 7 triaxial tests).

Analysis of test data is done in the Lab Data View.

RocProp Database

RSData includes RocProp, a database of intact rock properties that runs as a standalone application. RocProp contains over 700 test records from credible sources, including compressive strength, tensile strength, elastic properties, Hoek parameters, and velocity parameters. The database can be searched and filtered in various ways and allows users to add their own data to the database. The main features of RocProp are as follows:

  • Primary Database
  • Searching Records
  • Viewing Records
  • Charting and Statistics
  • User Database
  • Export to Excel
