岩石强度特性的单轴压缩试验研究

Study on Rock Strength Characteristics Based on Uniaxial Compression Tests

以宜兴抽水蓄能电站所提供的岩芯为例 ,对该电站岩芯的强度特性进行研究 ,依据单轴压缩试验结果分别提出了风干状态下岩石的单轴抗压强度与高径比 ,自然状态、饱和状态下岩石的单轴抗压强度与横截面积之间的非线性关系式 .

A study is performed on strength characteristics of rocks from the Yixing Pumped Storage Station. Some formulae are presented which reflect the non linear relationships between uniaxial compressive strength and the height to diameter ratio of rocks under air drying condition, and between the uniaxial compressive strength and the cross sectional area of rocks under natural and saturation conditions. The formulae provide some reference for estimation of strength of similar rocks.
