N2 - In this paper, the formation of flower structures and the Riedel shear structures inside a ground above a strike slip fault were reproduced numerically using the soil-water coupled finite deformation analysis code GEOASIA that mounts the SYS Cam-clay model on it. The analysis results revealed that the Riedel shear structures accompanied by flower structures developed as a bifurcation mode triggered by initial imperfections showing plastic expansion with loss of overconsolidation on the shear bands.
