【摘要】 基于花岗岩的真三轴强度试验结果和双剪强度理论,考虑岩石在三轴压缩状态下和在三轴伸长状态下不同的强度特性,导出了花岗岩在三轴压缩状态下的c8t函数关系式和在三轴伸长状态下的t8t函数关系式,并分别将目前常用的Gudehus-Arygris、William-Warnke、郑颖人、俞茂宏-刘风羽等角隅模型的屈服强度计算结果与花岗岩的真三轴强度试验结果进行了对比,得出了这些角隅模型能较为准确地预测屈服强度等一些有益的认识。更多还原

【Abstract】 Given double shear strength theory and true triaxial strength test data on granite, considered different failure strength characteristics of rock for triaxial compressive and triaxial tensile loading test paths, then granite corresponding functionsc8tunder triaxial compressive state andt8tunder triaxial tensile state are expressed separately. By compared granite true triaxial strength test results with predicting results which are obtained by different smooth ridge models, such as Gudehus-Arygris model, Zhen Yingren model, William-Warnke model and Yu Maohong-Liu Fengyu model etc., some beneficial suggestions on these smooth ridge models are proposed.更多还原
