| 摘 要： | 对锦屏II级水电站辅助交通洞的绿片岩进行单轴压缩蠕变特性试验，并以绿片岩和大理岩互层的层状岩体为研究对象，采用FLAC3D对互层状岩体进行单轴压缩蠕变试验的数值分析。试验和数值分析结果表明：当大理岩夹层倾角小于60°时，互层状岩体的破坏强度随着夹层倾角的增大而减小，但当夹层倾角大于60°时，互层状岩体的破坏强度反而随着夹层倾角的增大而增大；当大理岩与绿片岩之间的破坏强度比值较小时，采用Reuss模型和Voigt模型预测复合层状岩体的破坏强度是合适的。

| Abstract: | The uniaxial creep tests on greenschist from auxiliary tunnel at Jinping II hydropower station are carried out. Taking the interlayered rock mass composed of greenschist and marble as subject，the numerical analysis for uniaxial compression creep test on interlayered rock mass is conducted by using FLAC3D. The experimental and analytical results show that the failure strength of interlayered rock mass decreases with increasing dip angle of marble interlayer when the dip angle is smaller than 60°，while the result will be quite on the contrary when the dip angle is larger than 60°. Reuss model or Voigt model is applicable for forecasting the failure strength of interlayered rock mass when the failure strength ratio between marble and greenschist is small. |
