摘要
针对蚀变岩的特殊性,将西南某水电站工程中的蚀变岩,采用不同的方法进行了物理和水理性质试验、直剪试验研究。实验结果表明,岩石的内聚力和内摩擦角均与孔隙度、含水率有密切关系,回归分析显示,蚀变岩的内聚力、内摩擦角与含水率、孔隙度之间具有很好的乘幂关系。
According to the special nature of altered rock that comes from a hydropower project in the southwest,this article,using different methods,made the physical nature of arguments and water testing,direct shear test study.The experimental results demonstrate that the cohesion and the internal friction angle of altered rock has a closely correlation with the porosity and water content.Through the regression analysis,the cohesion and the internal friction angle of these altered rock has a power relationship with...
