摘要：
Modified rubber powder-cement mortarwas used to simulate the real rock. Glass fiber reinforced plastics (GFRP) was chosen as the bolt material. Reinforced effect of bolt to jointed rock mass under uniaxial tension was studied by laboratory test. The experimental results show that bolts enhance the uniaxial tensile strength of the jointed rock mass. Residual strength was found for all the reinforced specimens at the post-failure stage. Due to the reinforcement effect of the bolt, failure modes were different for reinforced specimen with different anchorage position.
