WALLAP is a powerful, fast and user-friendly program for analysing the stability of cantilevered and propped retaining walls. WALLAP is suitable for the analysis of both temporary works, such as sheet pile walls, and permanent works such as reinforced concrete diaphragm walls and contiguous bored pile walls.

Factors of safety are computed according to standard codes of practice while wall displacements and bending moments are calculated by a finite element analysis which models the actual sequence of construction of the wall. Earth pressures are calculated automatically from basic soil properties.
The strata profile consists of up to 100 soil types with hydrostatic or non-linear water pressure distributions. Surcharges may be applied and removed while struts and anchors may be installed and removed. The program is menu driven with context sensitive Help and on-line access to the comprehensive User Manual giving detailed guidance on data input and interpretation of results.

Can sheet piles be Fixed AND free earth support? Wallap vs manual calculations
I am using Wallap for the first time and have come across something strange. The design is a propped retaining sheet pile wall.
The bending moment and displacement diagrams indicate that it is free earth support. However, the net pressure diagram shows the passive pressure changing to active right at the bottom of the pile – indicating fixed earth support.
When I manual calculate the design using free earth method, I also get a prop force 27% LESS than the Wallap prop force.
The only difference I can see is the Wallap reports a drop in passive pressure for some reason at the bottom of the pile.
Can anyone please explain why/how:
1) A manual calc can be less than the wallap report in terms of resistance required (i.e. I thought Wallap would have optimised the force)
2) Why the net pressure changes from passive to active right at the bottom of the pile (even though the bending and deflection diagram shows free end)
