ABSTRACT

Procedures for analysing the foundation sliding stability of gravity dams are briefly reviewed. Attention is drawn to uncertainties concerning methods of analysis on the one hand and those concerning geological details and material parameters on the other hand. The influence of an initial stress field in the foundation on sliding stability analysis is explored by considering a relatively simple situation when the potential failure plane or weak seam in the foundation is horizontal. A new procedure for sliding stability analysis which makes use of in-situ or initial ground stresses is then outlined. Finally recommendations are made concerning the use of alternative simple or sophisticated methods of analysis.
