| 摘 要： | 通过对某边坡岩体原位直剪试验的数据分析,得到了岩体的抗剪强度指标(c和φ)和岩体原位直剪的剪应力—应变关系曲线。试验结果还表明:岩体的抗剪强度和残余强度与法向应力近似成正比例关系,再一次验证了库伦强度准则的正确性。

| Abstract: | By analysising the dates of In-situ direct shear tests of slop rocks for certain deep excavation,the shear strength parameters（c and φ） for the slope rocks are gotten and the shear stress-shear displacement relationcurves are obtained.The test results also show that：both the shear strength-normal stress relationcurves and the residual strength-normal stress relationcurves are approximative linear curve,so,the Coulomb strength criterion has been proved once again. |
