INTRODUCTION

Whatever the type of dam built on a rock foundation the geotechnical properties of the rock mass have to be clearly recognized and understood as they may play a vital part in the behaviour and safety of the structure and its associated rock slopes. Fortunately, after the designer has fully acquainted himself with these properties and has pointed out those which are detrimental, he can take a number of corrective actions to safeguard the satisfactory behaviour of the dam and its rock surrounding as a. whole. The selection of the proper treatment is based on a delicate balance between cost and safety, which is still often open to personal judgement rather than to rational conclusive proof. It is therefore of interest for the profession to inventory and discuss the various foundation and slope treatment methods, currently or even seldom used, for correcting rock deficiencies. It is the very purpose of Theme V of this Symposium.
