【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。更多还原

【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.更多还原
