摘    要:采用动力有限元软件,对所选工程实例中的岩质高边坡危险滑移面节点动应力进行计算,并与相应节点的静应力叠加,通过稳定系数公式计算出边坡滑体各时刻的稳定系数,得出边坡动力稳定系数时程曲线.工程应用表明,该稳定系数用于衡量边坡爆破开挖时的安全性切实可行.

关 键 词:ANSYS  滑动面  稳定系数  失稳

Abstract:This study calculates the dynamic stress on the nodes of the critical slip surface of a high and steep rock slope in an engineering example by means of ANSYS,a dynamic finite element software.By adding dynamic stress to static stress,and substituting the result into the formula to calculate the stability value of the moment,it has obtained the dynamic stability value time curve of the slope.The results show that it is reasonable and practicable to judge the security of slope blasting through the dynamic sta...
Keywords:ANSYS  sliding surface  stability value  instability
