Sheet walls are relatively thin, vertical structures, embedded in terrain to a depth sufficient to support an uphill embankment/downhill excavation thrust, including water and surcharges.
This type of structure can be constructed of driven prefabricated steel pile sections, adjacent, bored cylindrical piles, and reinforced concrete sheet elements usually produced on site.

Methods used for analysis / verification are: Limit equilibrium (LEM) and Finite Elements (FEM).
The program enables both cantilevered and propped structures to be analysed with the following features:

Computation according to Finite Elements or Limit Equilibrium methods even nonliner analysis.

Both piles and minipiles may be used in single or double file or quincuncial. Alternatively setts with single/double reinforcement.
Trace of flow envelope with computation of seepage volume
Analysis in presence of seism and/ or water table.
Sites with any number of soil layers.
Uniform, strip or point loads on the embankment may be defined.
Loads may be defined to act directly on the wall or placed at other depths.
Automatic calculation of the depth of embedment.
Verification of wall where depth is predetermined.

Thrust computation using COULOMB, Mononobe & Okabe  or RANKINE methods.
BOUSSINEQ’s method for subsoil pressures induced by external loads.
Simulation of excavation stages with displacements at each stage.
Any number of tiebacks/anchors.
Design of pile cap beam (ridge beam
Cost calculation of the design.
Analysis of global stability using FELLENIUS; , BISHOP; JANBU; BELL; SARMA methods
Sizing of pile reinforcement steel.
