EVALUATION OF STABILITY OF A RESERVOIR EMBAMKMENT IN A HIGH SEISMIC ENVIROMENT

摘要：

An effective-stress and non-linear approach was used for the seismic analyses of the Piedmont Reservoir embankment for a magnitude 7.5 design earthquake with peak acceleration of 0.7g. A plasticity constitutive model was used to simulate soil behavior. Computed performance was compared with observations during 1989 Loma Pieta earthquake. Analyses for the design earthquake indicated the potential for liquefaction and excessive deformation at the end of earthquake shaking.
