NEUTRAL PRESSURES INCREMENT IN THE SEISMIC FIELD

In the case of seismic, the increment of the neutral pressures produced by the deformations induced by the seismic waves is estimated. 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.

COMPUTATION OPTIONS

    • Recalculate function to evaluate the safety factor of a specific surface with centre X0, Y0 and radius R;
    • Identification of the critical slide surface through automatic calculation;
    • Computation of safety factor for surfaces which pass through two given points and are tangential to a straight line whose gradient varies automatically;
    • Automatic computation of safety factor for surfaces that are tangential to a straight-line vector;
    • Computation of safety factor for surfaces which pass through either three, or one given point;
    • Differentiation between flexible and rigid retaining structures;
    • Stability analysis of submerged slopes (e.g. hillside lakes);
    • Analysis of irregular surfaces;
    • Presence of seismicity and aquifers;
    • Stratified terrains and relative pore pressures;
    • Anisotropic Analysis;
    • Dynamic analysis Newmark.

GRAPHIC OPTIONS

    • Display of the safety factor isolines;
    • Coloured display of all sliding surfaces divided by safety factor (to each colour are assigned the safety factors in a fixed interval);
    • Selection of the surfaces to be printed;
    • Options <Delete mesh>, <Move mesh> and numerical assignment of the centeres’ mesh;
    • Option <Translate groundwater>, which allows to raise or lower the water table (handy command for the sensitivity of the Fs when the groundwater level varies);
    • Layer filling with textures or colours (the user can define the textures);
    • Graphical and numerical input for non-circular sliding surfaces;
    • Tools for inserting text, lines and polygons on the graphic sheet.

ADDITIONAL FEATURES

Dynamic Analysis: Newmark’s method was used to analyze slope stability under seismic conditions for direct integration and modal superposition (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, a free app for Geostru users. The sections to be analyzed with Slope are automatically created dynamically by moving on the 3D model.

DEM – Discrete Element Method: Advanced numerical method for analyzing slope stability in static and dynamic conditions. A very sophisticated model of computation of linear and nonlinear analysis based on the behaviour of the ductile or fragile soil.

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

    Software di facile comprensione e applicazione . Permette di realizzare diverse tipologie di analisi in maniera piuttosto semplice con ottimi risultati. Da migliorare le modalità di inserimento e rimozione degli interventi e le possibilità di composizione della relazione, ad esempio potendo selezionare solo un certo numero di superici.

  15. Andrew Hurley (verified owner)

    I have been using Slope for a few years now, but only infrequently and on reasonably straightforward problems. Even so, it does everything I need it to and at a price point that makes sense given my infrequent use. I am very happy with the support from GeoStru, they always respond in a timely manner and have always resolved my issues.
