RocData is a versatile toolkit for the analysis of rock and soil strength data, and the determination of strength envelopes and other physical parameters. RocData now includes RocProp, a database of intact rock properties that runs as a standalone application.
RocData can be used to 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. RocData utilizes 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 by RocData 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. RocData 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 by RocData can be used as input for numerical analysis programs such asRS2 (finite element stress analysis and support design for excavations) and Slide (limit equilibrium slope stability analysis).
RocData now includes RocProp, a database of intact rock properties that runs as a standalone application. RocPropcontains 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.
