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.
