摘　　要：考虑爆破地震的时程效应,采用拟静力化的惯性力法,利用改进了的条分法来计算主动土压力,提出了土质边坡在爆破过程中的动力稳定性系数的计算方法,再用改进的JC法求出土坡最小稳定性系数和最小可靠度指标。实践证明,本方法是一种准确、实用的土坡稳定性计算方法。By considering the time effect of blasting vibration and using the quasi-static method and the improved slice method, this paper puts forward an analytic method of slope stability under the action of blasting vibration. The minimum safe factor and reliability index are calculated by the improved JC method. The calculation results of an actual engineering slope show that the presented method is efficient and accurate for calculating the reliability of soil slope dynamic stability.
