摘　　要：岩质边坡在爆破开挖过程中的稳定问题是一个亟待解决的重要问题。对实际工程进行监测,得到适合该地区的能反应高程效应的爆破地震波传播规律,并采用拟静力法计算爆破地震惯性力,提出边坡在爆破动力作用下稳定安全系数的新计算方法———积分法,同时使用MATLAB程序搜索边坡最危险滑裂面并计算最小安全系数。实例证明,此方法是分析边坡动力稳定性的有效方法之一。The stability of rock slope under the effect of blasting excavation is so important to be solved urgently. After the blasting test on the actual project, the propagation rule of blasting wave is obtained, which can take the elevation effect into account. Using the quasi-static method to calculate the inertia force of blasting. The integral method is put forward to analyze the dynamic stability of slope under the effect of blasting vibration for the first time. Besides, it searched the most dangerous sliding surface and gained the minimum safety factor through the program of MATLAB. This method is proved to be one of the most valid methods to study the dynamic stability of slope through the sample.
