| 摘 要： | 针对江苏宜兴抽水蓄能电站提供的石英砂岩、砂岩、灰岩岩石试样进行抗压强度特性试验研究．依据岩石单轴压缩试验结果，将灰色预测改进GM(1，1)模型与跳变灰过程理论耦合，建立了风干状态、自然状态、饱和状态下岩石的单轴抗压强度与试件高径比之间的非线性关系式，利用该关系式可以很方便地在相关岩土工程中为相似岩石估算其强度值提供参考、借鉴．

| Abstract: | An experimental study is performed on the compressive strength of quartz sandstone, sandstone, and limestone samples from the Yixing pumped-storage power station. According to the test results, nonlinear equations for the relationship between the uniaxial compressive strength of rocks and length-to-diameter ratio of the samples are developed for the air-dried state, natural state, and saturation state by coupling of the improved grey model GM (1,1) with the jumping grey theory. With the equations, some references can be conveniently provided for prediction of the compressive strength of similar rocks in related geo-technical projects. |
