摘    要:从坡体破坏的摩尔—库仑准则和Hoek-Brown准则入手,分析了预应力施加对碎裂结构岩体抗剪强度的改善机制;结合实际工程,利用锚索的现场应力跟踪监测资料,通过对不同锚固应力、不同时间预应力损失值的相关性分析,提出了预应力损失值的变化规律。

关 键 词:边坡工程  滑坡体  预应力锚固效应  变化规律  锚索预应力  预应力损失值

Abstract:According to the Moore - Coulomb rule and Hoek- Brown rule on Slope- destruction,combining the reinforcing technology of prestressing anchor pole or anchor rope widely used in civil engineering, such as underground grotto, high side- slope, dam, pier and so on, the improving system of shear- resist strength exerted to the rock by prestress is analyzed. Having the aid of statistical monitoring data of field -working stage, the different anchoring stressand the prestress is loss in different time have been studied in this paper. A varying regulation of prestress loss and some significant conclusions and working proposals are proposd.
Keywords:prestress  anchorage  moore - coulomb rule  hoek - brown rule
