This program carries out the analysis of soil or rock slope stability both in static and seismic states utilizing the limit equilibrium methods of Fellenius, Bishop, Janbu, Bell, Sarma, Spencer, Morgenstern & Price and Discrete elements method (DEM) 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.
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 Nonstationary Earthquake Ground
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). 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).

NEUTRAL PRESSURES INCREMENT IN SEISMIC FIELD
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.
