| 摘 要： | 岩体具有不同程度的各向异性。对现场取样的各向异性岩石进行了单轴压缩试验,确定了描述岩石横观各向同性特征的5个弹性常数以及各向异性岩石的强度指标,并分析了各参数的变化规律。研究结果可为各向异性岩体工程计算和分析提供参考依据。

| Abstract: | Anisotropy exists in a rockmass with different scales.Based on anisotropy rock sampled from the situ,the uniaxial compression tests were performed.Five elastic constants which were used to describe the characteristic of anisotropy rock and strength index of anisotropy rock were determined by the tests,and the changing rule of these constants was analyzed.This experiment results can provide a references to calculate and analyze anisotropic rockmass engineering. |
