ral emgine~ing properties. Aspects of sampling and testing of various types of till are considered. The design of pile foumdations in cohesive ar~ granular till is reviewed. Design procedures are related to the results of back-calculated parameters from a large nt~mber of pile tests. Set~@lement prediction of a sir~le pile is considered on a simple comparative basis. A final section deals with pile selection and Inatallation in till. 63 refs. Avail: CIRIA, 6 Storeys Gate, London, SWlP 3AU, UK

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
