Study on the Potential Earthquake Deformation of Active Fault and the Safe Distance of Important Project Site to Active Fault

Without considering surface covering layer,the surface earthquake dislocation and strain distribution near active fault were calculated under different conditions of magnitude,fault movement style and fault dip angle using 3-D finite element method.Based on above results,the safe distance of active fault to important project site was studied.The results show that the fault characteristics,fault movement style,earthquake magnitude,site location and the anti-earthquake defensive requirement of projects are all key factors to determine the safe distance of project site to active fault.
