Overview

Slide2 is a powerful 2D limit equilibrium slope stability analysis program developed by Rocscience. It is designed to evaluate the safety factor or probability of failure for both circular and non-circular failure surfaces in soil or rock slopes. Slide2 incorporates various analysis methods, including vertical and non-vertical slice techniques, and supports complex modeling scenarios with ease. The software includes built-in finite element groundwater seepage analysis for both steady-state and transient conditions, eliminating the need for separate programs. Additionally, Slide2 offers extensive probabilistic modeling features, allowing users to define model input parameters as random variables to calculate the probability of failure or reliability index. Sensitivity analyses can also be performed to assess the impact of parameter variability on slope stability.
