The weak strength of fault rocks should be considered for assessing the stability of infrastructure near fault zone and the weak strength is originated from the discontinuities, and fabric orientation of fault rocks. The previous studies of the embedded anisotropy in fault rock are usually based on 2D analysis, for example, the thin section method, so that the procedure requires much time and extensive workload. In this study, we propose a statistical method called 'Slicing Plane Method (SPM)' which gives the major anisotropy induced by its structure. Also, it is confirmed that the anisotropy of structure is related to the reduction in the shear strength of fault gouge.
