摘　　要：本文采用相似材料模型试验方法研究了单根预应力锚索对均质岩体的加固效应，给出了在三种不同长度的锚索作用下，岩体中受力变形规律，分析了锚索长度、预应力数值等对加固效应的影响，并与有限元计算结果作了对比。In this paper,the reinforcement effects on homogenous rock by a single prestressed cable are investigated with model test.The distribution of the stress and strain in rock mass is obtained and some main parameters sucll as the length and prestress of the cables which affect the reinforcing effects are also analysed.The results of the tests are consistent with that by FEM.
