摘要
以宜昌—巴东高速公路凉水井隧道区出露的石膏质岩为研究对象,采用三轴伺服机开展了不同含水状态下的三轴压缩试验,研究围压及含水状态对石膏质岩强度的影响。
Gypsum rock exposed in Liangshuijing tunnel excavation area of Yiehang--Badong Expressway is taken as the research object. In order to study the effect of confining pressures and moisture contents on the strength of gypsum rock, the triaxial compression tests of gypsum rock under different moisture contents are conducted by using triaxial servo machine.
