A large number of high rock slope will be met in the highway construction process, the commonly used method of excavation is blasting excavation. Slope stability problems are the focus of attention for the project, when the blasting excavation was conducted. Numerical simulation of bursting excavation for the high rock cutting slope was carried out through finite element numerical method in the paper. The influence of blasting excavation on slope stability were analyzed systematically under different blasting parameters and different slope ratio conditions.%在高速公路建设过程中会遇到大量的岩质高边坡,常用的开挖方法是采用爆破开挖.而在爆破开挖时,高边坡的稳定性问题为工程关注的重点.本文通过系统的有限元数值方法,对岩质路堑高边坡的爆破开挖过程进行了数值模拟,系统地分析了不同爆破参数和不同边坡坡比条件下爆破开挖对边坡稳定性的影响.
