Abstract

 In the present study, a numerical method for analyzing the performance of an earthquake-resistant stone masonry retaining wall is developed. The Smoothed Particle Hydrodynamics (SPH) method and the Distinct Element Method (DEM) are combined in the developed method. In order to verify the developed method, a series of laboratory tests of earthquake-resistant stone masonry retaining walls are analyzed. The effectiveness of a ground reinforcing material are reproduced qualitatively by the developed method, however improvement is still required.
