中文摘要：

利用高精度μCT225KVFCB显微CT试验系统和JL型微机控制电液伺服万能试验机,对钙芒硝单轴压缩力学特性进行了研究。研究表明：钙芒硝压密阶段不明显,且存在刚性阶段;钙芒硝单轴抗压强度平均为7.54 MPa,属于软岩,其单轴抗压强度随着物质密度的增大而增大,随物质密度不均匀程度增大而减小,且与X射线衰减系数、衰减系数方差呈线性拟合关系。

英文摘要：

The experimental study on the uniaxial compressive mechanical properties of glauberite was carried out by high-precision Micro-CT μCT225KVFCB test system and JL computer-controlled electro-hydraulic servo compression test system.The results of studies showed that compaction phase was not obvious and there was a stiffness phase in the test.The average of uniaxial compressive strength was 7.54 MPa.The glauberite is a kind of soft rock.The uniaxial compressive strength of the glauberite increased with the increase of its density,but decreased with the increase of inhomogeneity of its density,and was fitted linear relationship with the attenuation coefficient of the diagnostic X-rays and the variance of the attenuation coefficient.
