Methods of Analysis ( Top
out two types of analysis within the one program:
- Limit equilibrium
analysis for calculating factors of safety against sliding and
of bending moments and shear forces in the stem and base (including
the effect of earth pressures due to compaction), and the bearing
pressure on the base of the wall.
Wall Geometry ( Top
A wide variety
of wall geometries can be analysed including variable heel and
toe width, battered front and back faces and a shear key at any
position. Gabion wall geometry can also be entered with up to
20 layers, with varying width, height and offset from the toe.
Soil Properties ( Top
Up to 20 soil
strata may be defined. For each stratum the following parameters
may be specified:
- Friction angle
- Earth pressure
due to compaction
- Earth pressure
The program will,
if desired, calculate earth pressure coefficients from values
of soil friction, wall friction, batter angle and backfill angle
given by the user.
Water Pressures ( Top
non-hydrostatic water pressure profiles may be defined on both
sides of the wall.
be specified to act on or below the ground surface on the active
and moment loads may be applied to the top of the wall. Horizontal
and vertical components of anchor load may be applied to the face
of the wall.
Both pre-defined EC7 factor
sets, and user defined factor sets can be applied to load cases. Factors are
applied to loads, surcharges and soil properties.
Units ( Top
Data may be entered
in any consistent set of units e.g. (kN,m), (lb,feet). All print-out
from the program is automatically annotated in the appropriate
Output ( Top
from the program consists of the input data followed by details
of the forces, factors of safety, wall pressures, bending moments
and shear forces.

The data can be edited interactively by clicking and dragging.
Results are displayed in the form of bending moment, shear force
and wall pressure diagrams.
