ANALYSIS OF FOUNDATIONS IN SLIDING ZONES

THE INCREASING NUMBER OF SITES ON WEATHERED ROCK SLOPES INVOLVE STRUCTURES BUILT ON STRATA WHERE THERE IS EVIDENCE THAT SLIDING HAS OCCURED. IN STEEPLY SLOPING TERRAIN, GEOLOGICAL AND SUBSURFACE INVESTIGATIONS FOR BUILDING SITES MAY SHOW ADEQUATE GENERAL STABILITY OF THE SLOPE, BUT INDICATIONS OF SURFACE STRATA MOVEMENTS. A BASIS FOR EVALUATING LATERAL RESISTANCE NECESSARY TO RESIST SLIDING ACTION IS AVAILABLE THEORETICALLY, IF DESIGN PARAMETERS ARE ESTIMATED FROM FIELD OBSERVATIONS. A FACTOR OF SAFETY IN RESPECT TO CREEP MOVEMENT MAY BE DEFINED. ACTUAL TESTS TO DETERMINE THE RHEOLOGICAL CHARACTERISTICS OF THE SLOPE MATERIALS ARE DESIRABLE. THE VARIOUS FACTORS INFLUENCING SLIDING AND THE EFFECT OF TIME ARE DISCUSSED. UTILIZATION OF A FACTOR OF SAFETY AGAINST CREEP IS PROPOSED FOR PREDICTING PRESSURES AGAINST WALLS. APPROACHES FOR ANALYZING THE PRESSURES INVOLVED ARE SUGGESTED. WITH PROPER ANALYSIS AND DESIGN, THE FOUNDATION OF A STRUCTURE IN A SLIDING ZONE MAY BE BUILT TO RESIST THE PRESSURES INVOLVED, OR BE ISOLATED FROM THE SLOPE MOVEMENT. MEASURES SHOULD BE EMPLOYED TO IMPROVE THE SLOPE STABILITY IN THE VICINITY OF NEW CONSTRUCTION.
