APPLICATION OF NONLINEAR SPECTRAL STOCHASTIC FINITE ELEMENT METHOD TO SURFACE EARTHQUAKE FAULT PROBLEMS

Abstract

 This paper presents the numerical simulation of reproducing model experiments of fault and actual surface earthquake faults. Suitable stochastic models are constructed for experimental samples and actual under-ground structures. It is shown that the fault conguration obtained by the simulation is in quantitative agreement with the observed one. The failure probability, which is a faction of input base slip, is computed from the simulation so that probability of fault formation is evaluated.
