Safe provides two-dimensional finite element computations in plane stress, plane strain, or axial symmetry. Pore pressures and effective stresses are identified separately, and gravitational loads and initial stresses are included.

Alp analyses the soil structure interaction of a laterally loaded pile. The program calculates deflection down the pile together with bending moments and shear forces within the pile.

Pile calculates the vertical load carrying capacities of a range of individual piles in a layered soil deposit. The theory is based on both conventional and new methods for drained (frictional) and undrained (cohesive) soils.

Pilset calculates the settlement of a single pile and surrounding soil under load and the displacement of surrounding soil.

Frew analyses flexible retaining structures such as sheet pile or diaphragm walls. The program calculates deformations and the stresses in the retaining structure through a number of construction stages from the initial installation of the wall through a series of activities such as variations of soil levels and water pressures, the insertion or removal of ground anchors and the application or removal of surcharges.

Greta analyses the stability of a gravity retaining wall and determines the bending moments and shear forces in the stem, heel and toe of the retaining wall. It also calculates the resultant force on the base and the sliding resistance.

Slope performs two-dimensional slope stability analysis to study circular or non-circular slip surfaces. The program uses the method of slices and offers a variety of established methods for calculating inter-slice forces, including the Fellenius, Bishop and Janbu methods.

Pdisp calculates the vertical settlements and stresses within a layered elastic soil mass arising from vertical pressure loading applied to rectangular and circular loaded areas. The program is ideal for predicting the settlement that may arise due to the action of several foundation loads at multiple levels.

Xdisp analyses the ground movements induced by tunnelling and embedded wall excavations in terms of three-dimensional displacements and horizontal strains. Ground movements arising from tunnelling may be analysed by four separate methods to create a profile of settlement at any level above the tunnel. Assessments of damage to buildings may be made.
