摘要
因多种原因需要计算有支挡结构的滑坡与边坡稳定系数;当稳定系数不满足要求时,需要对其支挡结构进行加固,这时还需要计算作用在加固结构上的荷载。本文提出了有支挡结构时滑坡与边坡稳定系数及加固结构荷载计算方法,这种方法将支挡结构及其加固结构的作用视为对滑坡与边坡提供的抗力(即有利于滑坡与边坡稳定的荷载),把有支挡结构的滑坡与边坡稳定系数计算与作用在边坡工程加固结构上的荷载计算分别视为有利于稳定的荷载作用下滑坡与边坡稳定性计算的正问题(已知荷载求稳定系数)和反问题(已知稳定系数求荷载)。
It is needed to calculate the safety coefficients of landslides and slopes with retaining structures for several kinds of causations,and it is also needed to calculate the loads on the reinforcing structures when it is plan to reinforce the retaining structures whose safety coefficients are not meet the demand.It is put forward the calculating method for the safety coefficient of landsides and slopes with retaining structures and of loads on the reinforcing structures where the actions of the retaining structures and their reinforcing structures are considered as the resistance for the landsides and slopes,which is the loads that are in favor of their stability.The calculation of safety coefficients of the landslides and slopes with retaining structures and the calculation of the loads on reinforcing structures are respectively considered as the natural issue（calculation of the safety coefficients by using the known loads）and the reversed issue（calculation of the loads by using the known safety coefficients）for the stability calculation of landsides and slopes with the loads in favor of their stability.
