对现场爆破情况分析知，顺层台阶爆破的抵抗线、炮孔装药量、软弱夹层含水率是影响边坡稳定性的主要因素。

Resistance lines, hole charge, moisture content of interlayer are the main factors to effect the slope stability in blasting of layered rock masses by analyzing site blasting.

岩体结构面对爆破效果有显著影响，当最小抵抗线与结构面平行时，极易造成冲炮和隔墙。

Rock joint has a strong influence on blasting result, when burden and fault are parallel, this easily results in rushing out of the chamber and partition wall.

采用瑞典条分法，进行滑坡体的稳定性检算，对药室装药量、爆破作用指数、最小抵抗线等参数进行设计计算。

The Sweden circle method is adopted for the stability analysis of landslide, and the chamber charge, blasting acting index and the minimum holdout line are designed and calculated.
