(9 customer reviews)

Slope stability software carries out the analysis of soil or rock slope stability both under static and seismic conditions, using the limit equilibrium methods of Fellenius, Bishop, Janbu, Bell, Sarma, Spencer, Morgenstern & Price, Zeng Liang and (DEM) Discrete elements method for circular and non circular surfaces by which it is possible to ascertain slippages in the slope, examine a gradual failure, and employ various models of force-deformation relationship. Reinforcements with piles, gravity and/or reinforced concrete bracing walls, nettings, geofabrics, anchors, and terracing may be specified. Distributed and point loads may be defined.

Rock slope analysis using the Hoek and Brown method (1980)


In case of seism is estimated the increment of the neutral pressures produced by the deformations induced by the seismic waves. The formulas used are: Matsui et al., 1980, Seed & Booker, 1997, Matasovic,1993. All the parameters necessary for the estimate such as Arias index, Trifunac duration, etc. are calculated automatically by the programme upon integration of the design accelerogram.

Additional features

Dynamic Analysis: Numerical method for the analysis of slope stability under seismic conditions for direct integration and modal superposition using Newmark’s method (1965). It allows the computation of permanent displacements of landslide mass by integrating the relative acceleration. It is also possible to generate the artificial accelerograms or import accelerograms from: SIMQKE and Sabetta F., Pugliese A.: Estimation of Response Spectra and Simulation of Non stationary Earthquake Ground Motions.

Slope 3D: Generation of digital 3D models from GIS, DXF or Text files. Import of files from SRTM (SRTM is a software created by GEOSTRU, included in the GEOAPP free suite, which allows the generation of a 3D model by simply selecting an area on Google Maps) of from GeoStru Maps, free app for Geostru users. The sections to be analyzed with Slope are automatically created in a dynamic way by moving on the 3D model.

DEM – Discrete Element Method: Advanced numerical method for the analysis of slope stability in static and dynamic conditions. Very sofisticated model of computation of linear and nonlinear analysis based on the behavior of the ductile or fragile soil.

M.R.E. (Mechanically reinforced earth): Design and verification of reinforced soil retaining structures. Are carried out verification at: pullout and break for bar or strips reinforcements and geosynthetics, local stability (Tieback), global stability (Compound), sliding verifications of a rigid body, limit load, overturning. Provided standards: NTC2008, GRI (Geosynthetic Research Institute), BS8006/1995 (Code of practice for strengthened/reinforced soils and other fills), FHWA (Federal Highway Administration).
