Some of the mechanisms giving rise to relic slip surfaces are described and site investigation and testing techniques required to furnish information for detailed analysis are considered. Methods of stability analysis are discussed and the importance of the porewater pressure regime is considered in the context of determination of factor of safety and remedial measures.

It is shown how t h e properties of the rocks and their variation in composition and state of weathering affect excavation, draluage, erosion control, side slope design and availability of pavement and concrete aggregates. ~he design of e~bsmkn~'nts on soft marine clays is outlined.
