ROCK SLOPE AND CLIFF STABILITY

STABILITE DES TALUS ROCHEUX ET DES FALAISES

ROCK MASS STABILITY GIVES RISE TO NUMEROUS PROBLEMS OF PROTECTION, REPAIR AND DESIGN DUE TO THE EVOLUTION OF NATURAL SLOPES, THE CREATION OF ROCK CUTTINGS OR THE INTRODUCTION OF EXTERNAL FORCES IN THE CASE OF STRUCTURAL FOUNDATIONS MODIFYING CONDITIONS OF NATURAL EQUILIBRIUM. THE STUDIES STARTED IN THIS FIELD WILL BE CONTINUED IN 1979 AS FOLLOWS: - IMPROVEMENT IN METHODS OF STABILITY ANALYSIS BY DEVELOPMENT OF MATHEMATICAL MODELS TAKING INTO ACCOUNT THE INFLUENCE OF DILATANCY; APPLICATION TO THE ANALYSIS OF REAL CASES; CONTINUATION OF THE DEVELOPMENT OF THE IN-SITU DETERMINATIONS OF THE GEOMETRY OF THE SURROUNDING ROCK; - DEVELOPMENT OF NON-DESTRUCTIVE TESTING AND SURVEILLANCE TECHNIQUES OF ROCK MASSES (IMPROVEMENT IN TELEMEASUREMENT TECHNIQUES, DEVELOPMENT OF FINE MEASUREMENT OF TILTING, CONTINUATION OF THE STUDY OF SEISMIC-ACOUSTIC MEASUREMENTS); - DEVELOPMENT OF A MODULAR DATA PROCESSING PROGRAM FOR TREATING SUCCESSIVE STAGES ON VDUS; - STUDY OF THE INFLUENCE OF ROCK WEATHERABILITY ON THE STABILITY OF ROCK MASSES; - STUDY OF THE STRUCTURE OF ROCK MASSES: CRITICAL ANALYSIS OF DETECTION METHODS, DESCRIPTION AND QUANTIFICATION OF DISCONTINUITIES WITH A VIEW TO STABILITY ANALYSIS.
