摘要
用有限元方法模拟研究断层构造对地应力场分布的影响。结果表明:断层规模、岩体、断层弹性模量、断层走向与区域最大水平主应力的夹角、边界应力比、断层几何形态等是影响断层端部以及附近应力场分布的主要因素。
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.
