Model
- Horizontal soil layers with different cohesion values on the active and passive side
- Ground surface horizontal, inclined or as a broken line
- Bottom of excavation horizontal, inclined or with a berm
- Horizontal water table on both sides of the wall;
hydrostatic or hydrodynamic water conditions.
- Closed or open wall systems with arbitrary bounding conditions at top of wall
- Vertical or inclined wall with variable bending stiffness

Construction States, Supports
- Construction process in stages
- Automatic evaluation of envelope results over all construction stages
- Fixed and elastic supports
- States "active" or "inactive" changable in the construction stages
(installation and removal of supports like props, anchors)
- The influence of support displacements can be studied
|
Loadings
- Constant superimposed load on the active and the passive side of the wall
(e.g. for dismantling stages)
- Uniformly distributed surface- and line loads
on the active wall side
- Earth pressure parts from loadings can be considered for the earth pressure
redistribution
- Concentrated and distributed loads on the wall
- Earthquake loads, horizontal and vertical

various load types

Earth Pressure, Calculation Models
- Calculation of earth pressures according to the theory of Coulomb
- Earth resistances according to Coulomb, Caquot-Kérisel or
Weissenbach
- Redistribution of the wall pressure down to excavation depth, point
of zero pressure or bottom of wall
- Redistribution shapes: rectangle or polygon
- Freely choosable component of the earth pressure at rest
- Widely accepted methods for calculating the embedded depth, the section
forces and displacements of the wall for a construction in stages
|
resulting wall pressure

Results
- Required embedded depth, if not predefined
- Support forces for anchors and/or props
- As graphic or table: wall pressures, shear forces, bending moments,
displacements
|
Envelopes of bending moments over all stages
|
Stability of Excavations
- Global stability and anchor lengthes can be checked
using the stability analysis module S
- All input data uf the excavation module including the
calculated support forces are automatically transferred to the stability module

Design of Cross Sections (option)
- The option complements the excavation module with design capabilities
for wall sections according to the SIA design codes
- The cross section can be selected from a list of parametrized sections
Cross Section Types Closed Wall
• Sheet pile wall
• Diaphragm wall
• Contiguous bored pile walls
Cross Section Types Open Wall
• Soldier pile walls
• Intermittent bored pile walls
