摘要

在满足边坡稳定安全的基础上，运用边坡稳定性分析中的传递系数法分析边坡推力分布特征，以边坡主下滑段为预应力锚索加固对象，考虑其上滑体的下滑推力和阻滑段的抗力作用，得出了求解加固段各条块预应力锚索抗力的计算公式，建立了预应力锚索设计荷载与其布置间距的关系，提出了一套土质边坡预应力锚索加固设计的方法，该方法形式直观、运用方便，可直接确定预应力锚索设计荷载与其布置间距，且边坡的稳定性能自动满足工程要求。用该设计方法对某工程进行了实例分析，取得了较好的效果。

Abstract

Distribution characteristic of thrust force of a slope is analyzed using transfer coefficient method for stability analysis of slopes. Main sliding sect of slope is considered as reinforcing object of the prestressed cable. Considering the resisting force of stopping slide sect and the thrust force of slope upper sect

the calculation formula of prestressed cable hold force and the relationship between prestressed cable design strength and its set distance are developed with the slope safety being satisfied in advance; and a design method of prestressed cable for soil slope is put forward. The method is simple in form and easy in application. It is shown that the design strength and the set distance of prestressed cable is directly made certain using this method; and that the stability coefficient satisfies engineering need automatically. Finally

an engineering project is illustrated

and good results are obtained.
