The solution is derived by uncoupling the load transfer for the pile into separate shaft and base components. The solution give~ the load-settlement ratio of the pile in terms of pile geometry and stiffness and soil stiffness. The solution is used to back-amalyse pile tests, enabling the soil stiffness profile to be eatlr~ted from loadsettlement measurements.

1978, P148~15~ Equations are derived that satisfy the equilibrium comditions for both forces amd momer~s for earth slopes subject to lateral acceleration. The equations are applicable to ar~ shape of failure surface and take into account the effect of interslice forces. Two methods of solving the equations are given, one using the factor of safety as the variable and the other using the critical value of lateral acceleration. Results obtained show that a log spiral failure arc is not more critical than a circular arc, stability is reduced if the lateral acceleration has a dowr~mrd component, and taking factor of safety amd acceleration factor as altermative criteria the critical slip circles are similar provided soil cohesion is small
