Abstract

The permanent ground displacement adjacent to the seismic fault is of great interest to many earthquake and structural engineers. The thin layer method is one of the advantageous calculation methods for the dynamic Green's function in layered soil, which can also be applied to the static problem in terms of a summation of the eigenmodes. Evaluation of ground displacement due to seismic faults requires stress component calculation, which is firstly verified. We use improved calculation method to calculate stress components using secondary elements. Finally, permanent ground displacements are verified to show the feasibility of the proposed calculation methods by comparing with rigorous solutions.
