摘　　要：在传统的基质吸力计算模型基础上,增加时间维变量,从而实现了基质吸力的动态计算,并将该方法应用于某露天矿边坡工程实例,为进一步边坡稳定性动态评价研究提供了依据。Based on the traditional method for the matric suction calculation, the time-dimension was taken into consideration to realize the dynamic calculation of matric suction. This dynamic simulation method was applied to an open pit slope, provide a foundation for further dynamic evaluation research of slope stability.
