考虑地震力作用的边坡水平推力计算
摘要:为了减少或者避免地震力作用下边坡破坏造成的损失,很有必要对地震力作用下边坡的稳定性和支护问题进行研究。为了计算地震作用下边坡对支挡结构的的水平推力,将地震力视为水平指向坡外的水平力,并假定边坡滑移面为直线的前提下,利用极限平衡法,推导了斜边坡与二阶竖直边坡水平推力的计算公式,并在此基础上总结出了一般边坡水平推力计算的统一表达式,可为支挡结构的设计提供水平推力。
Abstract:In order to reduce or avoid the losses of slope failures caused by earthquake, it is very necessary to study the slope stability and support issues under seismic forces. To calculate the lateral forces of the slope under the earthquake, the seismic forces as a horizontal force and the direction of the force point to the outside of the slope. With the assumptions that the slide surface is straight line, the lateral forces of slope are deduced by limit equilibrium method, and a general formula of the lateral forces is established. The lateral forces can be used to the design of retaining structures.
