摘　　要：对台阶滑动面上单元体进行受震分析 ,利用极限分析运动单元法确定边坡安全系数与爆破震动影响系数之间的关系 。The vibration of elementary units on the sliding surface of the bench are analyzed. The relationship between the slope safety coefficient and the blasting vibration influence coefficient is determined by analyzing the moving units through the limit analysis method. And further, the critical blasting vibration accelerator and the critical vibration speed are determined based on the dynamic influence of blasting on slopes.
