Deflection of an embedded cantilever wall in sand
The program provides estimates of long-term wall deflection and associated settlement for a cantilever wall in dry sand. The estimations are derived using pre-calculated movements determined by calibration of Finite Element predictions with movements measured in case histories (mostly in Perth's sandy soils). The methodology employed builds on the approach described in the following publication:

- Sand profiles only — the average Ic over the averaging band must be below 2.2.
- Water table at least 2·H below ground (where H is the excavation depth).
- The program idealises the input CPT qc data to the best-fitting linearly increasing qc with depth (dqc/dz).
- No load or material factors. Bending stresses in the wall section are not checked.
