When the mountain tunnel passes through the fault fracture zone, engineering geological disasters such as collapse often occur. In order to analyze the influence of fault fracture zone on the stability of tunnel surrounding rock, the finite element model is established by using ANSYS to simulate and study influences of fault dip angle and width on the stability of tunnel surrounding rock, the distribution laws of displacement field and stress field of surrounding rock under various working conditions are summarized, which provides reference for the design and construction of tunnel in fault fracture zone.
