ANALYSIS OF EARTHQUAKE INDUCED SLOPE FAILURES

RESEARCH ON CAP TYPE SOIL PLASTICITY MODELS DERIVED FROM WEIDLINGER ASSOCIATES' EXTENSIVE EXPERIENCE IN CONSTITUTIVE MODELING OF GEOLOGICAL MATERIALS IS PROPOSED TO HELP ANSWER THE URGENT NEED TO DEVELOP RATIONAL METHODS FOR THE PREDICTION OF EARTHQUAKE INDUCED SLOPE FAILURES. THE PROPOSED RESEARCH WILL CONCENTRATE ON THE DEVELOPMENT OFA CAP MODEL SPECIALIZED FOR SEISMIC ANALYSIS. THE RESULTINGSIMPLIFIED MODEL SHOULD BE ADEQUATE FOR DYNAMIC SLOPE STABILITY ANALYSIS WHILE, AT THE SAME TIME, EASILY USABLE BYA BROAD COMMUNITY OF ENGINEERS. IMPROVED INSIGHT INTO CONVENTIONAL METHODS OF SEISMIC SLOPE STABILITY ANALYSIS AND INTO THE DESIGN OF COUNTERMEASURES TOMITIGATE THE DAMAGE DUE TO SLOPE FAILURES ARE ADDITIONAL BENEFITS IMPLICIT IN THE PROPOSED RESEARCH.
