Assumes horizontal interslice forces are zero. It satisfies moment equilibrium but not force equilibrium. Best for circular slip surfaces.
Previous versions allowed separate seepage analysis. Version 70 introduced a more robust . You can now directly use pore pressures from a finite element seepage analysis within the limit equilibrium slope stability calculation without leaving the same project environment. For the "full" user, this means modeling complex transient seepage (e.g., rapid drawdown in reservoirs) with higher fidelity.
Over its release history leading into the 2021 updates (which laid the groundwork for modern iterations like Slide2), the software introduced features that transformed the speed and accuracy of 2D slope stability assessments. Cuckoo Search and Surface Optimization
The standard model utilizing cohesion and friction angle.
Once a critical slip surface is identified via standard or heuristic searches, Slide2 applies a surface optimization technique. This feature introduces local modifications to the slip surface vertices, adjusting the shape to find an even lower Factor of Safety. In the 2021 version, these optimization routines were further streamlined to cut down calculation times on multi-layered models. 3. Sophisticated Material Modeling rocscience slide 70 full 2021
A typical project workflow in Rocscience Slide 7.0 consists of three major phases:
An in-depth technical analysis of Rocscience Slide2 version 2021, exploring its core capabilities, 2D limit equilibrium slope stability analysis methods, material models, groundwater integration, and industrial applications.
A basic method that satisfies moment equilibrium but neglects all interslice forces. It provides a conservative estimate and is primarily used for historical comparison. 2. Advanced Search Methods for Critical Slip Surfaces
Modeled with explicit tensile strength, plate capacity, and pull-out resistance parameters. Assumes horizontal interslice forces are zero
: Features built-in finite element groundwater seepage analysis for steady-state or transient conditions.
Slide contains a built-in engine. Users do not need to switch to standalone hydraulic software to map pore water pressures. It handles: Steady-state seepage through embankments and earth dams. Transient flow to simulate rapid drawdown scenarios.
Grid Search, Cuckoo Search, Particle Swarm Optimization (PSO)
Engineers looking for the "full" ecosystem are typically evaluating the complete capability package—ranging from standard Limit Equilibrium Method (LEM) analyses to integrated Finite Element groundwater seepage computations. Core Engineering Capabilities Previous versions allowed separate seepage analysis
Slope stabilization is a key engineering activity. Slide 7.0 allowed for the direct modeling of most common support types. Users could define and apply:
: Execute the calculations. Open the interpreter application window to visually study the critical slip circles, slice-by-slice forces, and groundwater flow vectors. Slide Industry Applications
Models the bond strength between the grout, rock/soil, and steel tendon.
: This version brought robust feature updates, including cloud computing integration, Multi-Modal Optimization (MMO) , and direct connectivity to automated spreadsheet routines.
Slide2 features an integrated 2D finite element groundwater seepage analysis tool. Users can define hydraulic boundary conditions (such as total head, infiltration, or zero flux) and material permeability values. The software automatically computes steady-state or transient fluid flow, generating pore pressure grids that seamlessly feed directly into the slope stability calculations. This eliminates the need to export data between separate software programs. 5. Support and Reinforcement Modeling
