| Abstract: | 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. |
