摘要 本文对高温处理后的花岗岩试样进行分阶段降温处理,并对处理后的试样进行巴西劈裂试验。试验结果表明:经历高温处理后,花岗岩试样抗拉强度大幅减小;塑性变形增大,弹性阶段减小,温度对花岗岩的抗拉强度有着严重的劣化作用。 In this paper,the granite samples after heating treatment were cooled in stages,and the treated samples were subjected to the Brazilian split test.The test results show that the tensile strength of the granite sample is greatly reduced after heating treatment;the plastic deformation is increased,the elastic stage is reduced,and the temperature has a serious deterioration effect on the tensile strength of the granite.
