ALP

Alp analyses the soil structure interaction of a laterally loaded pile. The program represents the pile as a series of elastic beam elements and the soil as a series of independent springs. Maximum earth pressure coefficients may be specified to model soil shear failure. Alternatively non-linear soil behaviour can be modelled as p-y curves which are generated or specified. The program calculates deflection down the pile together with bending moments and shear forces within the pile.

Program features include:

soil properties can vary with depth

water pressures may be either hydrostatic or piezometric

lateral loads or bending moments can be applied at any location down the pile

partial or full, lateral or bending moment restraint can be placed at any depth down the pile

the top of the pile can be above ground level

uniformly distributed surcharges can be placed at any depth

displacements can be imposed in the body of soil surrounding the pile.
