摘　　要：钻地弹侵彻爆炸条件下岩石边坡破坏问题与战时工程抢修紧密相关,采用极限刚体平衡法研究钻地弹侵彻爆炸条件下的边坡稳定性问题,通过等效静力法将爆炸震动惯性力进行静力等效,并且考虑震动衰减和震动惯性力的方向,最终得到了边坡稳定系数的确定方法。研究表明,稳定系数随着钻地弹侵彻位置、边坡坡角变化而变化。The damage problem of rock slopes under penetration and explosion of earth penetrating weapon is closely relative to engineering repairing in the war.The analysis of the stability of rock slopes under penetration and explosion has been done by resorting to the rigid body limiting equilibrium method in this paper.The inertia forces of the explosion vibration has been equivalent to static forces by using pseudo-static method with considering the main frequency decreasing and the pseudo-static inertia forces＇ direction,the caculating method of the stability coefficient has been gotten.The research shows that as the changing of the penetration point and slope angle the stability coefficient changes as well.
