Slope

|
|
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.
Automatic computation of Safety
Factor for surfaces that: are
tangential to a straight line (automatically
varying the inclination), that pass
through one, two, or three given
points. Analysis of submerged slopes.

INCREASE IN THE NEUTRAL PRESSURES IN THE SEISMIC FIELD
In the presence of a seism, the increase in the neutral pressures produced by
the deformations induced in the ground by the seismic waves is evaluated.
The reposts applied are the following: 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.
BREAKING MOMENTS OF PILES AND MICRO-PILES
Automatic calculation of the yield moments of the circular sections, including
the mixed ones.
