【摘要】 岩石不连续面抗剪强度是岩质边坡设计中极为重要的参数,作者讨论了利用岩石三轴压缩试验残余强度条件下计算岩石不连续面抗剪强度的试验方法。根据Jaeger单一不连续面强度理论可以得出,当岩石不连续面的角度为β =π/4+φ/2时,岩石将沿此不连续面发生破坏,岩石三轴压缩条件下发生的剪切破坏后的残余强度可以看作单一的不连续剪切面的剪切强度,即根据岩石三轴压缩条件下发生的剪切破坏后的残余强度可以得出岩石不连续剪切面的抗剪强度。更多还原

【Abstract】 Rock discontinuity shear strength is the design of rock slope is extremely important parameters,the authors discuss the use of rock triaxial compression tests of the residual strength calculation under the condition of rock discontinuity shear strength test method. According to Jaeger single discontinuity theory of strength can be drawn, as rock discontinuity plane angle for β =π/4+φ/2,the rock will be along the discontinuity surface damage,so the rock under triaxial compression in occurrence of the residual strength of the shear failure can be seen as a single continuous shear plane of shear strength of rock, namely according to the triaxial compression condition under the shear failure of the residual strength of rock discontinuity shear can be obtained and the shear strength.更多还原
