中文摘要:

通过对立方体红砂岩试样预置30°,45°和60°裂隙的试验,研究了不同锚固状况下含单裂隙岩样力学特性及其注浆与加锚控制效应.结果表明:注浆加固条件下的岩样峰值强度,裂隙倾角为45°时最小,30°时最大;加锚加固条件下的岩样峰值强度,裂隙倾角为60°时最小,30°时最大.

英文摘要:

Through the uniaxial compressive tests on cubic red sandstone samples preset with cracks of 30°,45° and 60°,the mechanical properties of rock samples with single crack under different anchoring conditions as well as the grouting and anchoring reinforcement effects were studied.The test results show that the peak strength of rock samples under grouting reinforcement is the smallest when the inclination angle of the crack is 45° and is the largest when the inclination angle of the crack is 30°.The peak strength of rock samples under anchoring reinforcement is the smallest when the inclination angle of the crack is 60° and is the largest when the inclination angle of the crack is 30°.
