Based on the detailed analysis on geological environment and fault zone distribution in the Yishu fault zone，the Yishu fault zone geological model is made of polycarbonate material. To simulate the specific structural framework of stress and strain fields，we used uniformed，concentrated and two-point loadings in photoelastic experiments. The seismic risk area in the Yishu fault zone is judged through photoelastic experimental data analysis and processing，which is based on the comparison of stress accumulation area and seismic hazard points in different loading ways.
