| 摘 要： | 针对岩盐这一特殊性质的岩石，进行了基本的力学特性试验，包括单轴压缩、间接拉伸及变角剪切。通过试验，发现无水芒硝岩盐是一种软岩，强度较低，变形较大。在单轴压缩变形破坏过程中，具有与普通岩石试件不同的四阶段性特征。另外，由变角剪切试验结果分别获得了无水芒硝和钙质芒硝岩盐的强度曲线方程。

| Abstract: | Testing study is made on the basic mechanical property of thenardite salt rock,which includes uniaxial compressive,indirect tensile and angle changed shear tests. Through the testing and analysis,it is found that thenardite salt rock is a kind of soft rock,the strength of which is low and the deformation is distinct. Moreover,the uniaxial compressive deformation and damage of thenardite are different from other rocks during four deformation phases. With variation of shearing angles,the strength curve equation of thenardite and calcium thenardite salt rocks are deduced. |
