Abstract The effect of fault structure on ground stress field is studied by using finite element method. The results indicate that, fault scale, elastic modeling quantity of a fault and rockbody, the angle between maximum horizontal principal stress and fault direction, stress border and fault geometry are the main factors of ground stress distribution at the ends and vicinity of a fault.
Key words ：
ends of fault
ground stress field
