Slide Program Overview

Slide is a 2D slope stability program for evaluating the safety factor or probability of failure, of circular or non-circular failure surfaces in soil or rock slopes. Slide is very simple to use, and yet complex models can be created and analyzed quickly and easily. External loading, groundwater and support can all be modeled in a variety of ways.

Slide analyzes the stability of slip surfaces using vertical slice or non-vertical slice limit equilibrium methods (e.g. Bishop, Janbu, Spencer, Sarma, etc). Individual slip surfaces can be analyzed, or search methods can be applied to locate the critical slip surface for a given slope. Deterministic (safety factor) or probabilistic (probability of failure) analyses can be carried out.

Features include:

Groundwater Analysis with Slide

Finite element groundwater (seepage) analysis, for steady state or transient conditions, is built right in to the Slide program. See the Groundwater Analysis with Slide topic for more information.

Probabilistic Slope Stability with Slide

Slide also has extensive probabilistic modeling and analysis features. Nearly all model input parameters can be defined as random variables, so that a probability of failure or reliability index may be calculated. Sensitivity Analysis can also be carried out. See the Probabilistic Analysis Overview topic for more information.
