| 摘 要： | 岩体单轴压缩强度是岩体稳定性分析的重要指标，推导了节理岩体的单轴压缩强度的理论计算公式，公式分别考虑了岩体的不同破坏形式，即沿节理面的滑动破坏和沿岩石内部的剪切破坏，并分析了节理面倾角对压缩强度的影响，得到随着节理面与加载方向夹角的增大．节理岩体的单轴压缩强度逐渐增大，并最终趋于定值的规律。

| Abstract: | The axial compressive strength of joint rock mass is an important index for the rock stability analysis; the theoretical equation for the axial strength of joint rock mass is deduced, the equation considers different failure modes, which are the slipping along the joint plane and shear failure in the rock; and the influence of the joint plane inclination to the compressive strength is analysis as well, which shows that with the increase of the angle between joint plane and loading direction, the axial compr... |
