对某一特定的边坡计算模型,采用数值计算方法进行边坡地震响应分析,比较坡体内各点及地面参考点的地震响应,可以获得边坡体的地震加速度峰值放大系数;将加速度放大系数与地面设计加速度的乘积作为该点的水平加速度,采用数值计算方法计算得到边坡的最危险应力状态;拟定系列潜在滑面,分析潜在滑面的安全系数,以评价边坡的地震动力稳定性。
The magnifying coefficient of earthquake acceleration peak value could be obtained, using numeric calculation method to analyze the earthquake response and compare inner points with ground reference ones in earthquake for a certain slope model. The most dangerous stress state of the slope could be obtained, using numeric calculation to multiply the acceleration magnifying coefficient by ground designed acceleration as the level acceleration of a point. In order to estimate the earthquake dynamic stability of a slope, the potential sliding faces were enacted and their safety factors were analyzed.
