Sensitivity and Numerical Analysis Using Strain Space Multiple Mechanism Model for a Liquefiable Sloping Ground
In this paper a model is developed to examine the geo-material variabilities and earthquake motions after calibrating the model by carrying out class C numerical simulation based on dynamic centrifuge test on a liquefiable sloping ground using Ottawa F-65 sand. The constitutive model parameters were derived from the result of cyclic torsional shear test carried out at a relative density of 60%. Following the successful validation with the centrifuge test, the constitutive model is used to carry out sensitivity analysis to ascertain the effect of various uncertainties including the material variability present in situ conditions. In order to understand the behavior of a liquefiable sloping ground under realistic scenario earthquake input motions, a numerical study is also performed under 1995 Kobe and 1989 Loma Prieta earthquake motions and the soil system response is compared.
