How to model a slope in cSlope, run the analysis and report the result.

cSlope is limit equilibrium software for the stability of slopes, embankments and cuttings. This documentation explains each part of the program and walks through complete analyses in the tutorials.

Where to start

• New to cSlope: install it, read the cSlope window, then follow the tutorial Your first analysis.
• Looking for a particular dialog or option: use the menu on the left. The pages follow the order in which a model is built.
• Checking how a result is computed: the theory page gives the equations, and the verification page compares cSlope with published solutions.

How an analysis is built

1. Geometry: draw the exterior boundary of the section and the boundaries between materials, or import them from a DXF drawing.
2. Materials: define the soils and assign one to each region.
3. Water: add a piezometric line, and lines for individual materials if needed.
4. Loads and reinforcement: add distributed and line loads, anchors, nails, geosynthetics and piles.
5. Search: set where slip surfaces may enter and exit, or define your own.
6. Analysis options: choose the method, the number of slices and any tension crack or partial factors, and run the analysis.
7. Results and reporting: inspect the critical surface and the forces on its slices, annotate the view and export it.

Sensitivity and probabilistic analysis build on a finished model.

Units

cSlope works in SI units: lengths in metres, stresses and strengths in kPa, unit weights in kN/m³ and forces in kN per metre run. The unit weight of water is 9.81 kN/m³.
