SPH SIMULATION OF SLOPE FAILURE INDUCED BY EARTHQUAKE GROUND MOTION

Abstract

 The finite element analysis is hardly applicable to simulation of slope failure because of insufficiency of handling large deformation. The smoothed particle hydrodynamics (SPH) which is known as a powerful simulation tool for large deformation problem is applied to the earthquake induced slope failures simulation. Firstly, a new SPH form of the equation of motion which improves an accuracy of earthquake response analysis is proposed. Secondly, the Rayleigh damping is introduced to the SPH simulation successfully. Thirdly, it is shown that the process of development of a failure line is affected by the SPH particle density and the Rayleigh damping.
