摘要
本文以高温加热后水冷处理花岗岩试样为研究对象,并对处理后的花岗岩试样进行卸围压试验,试验结果表明:经历高温处理后,花岗岩卸围压试验应力—应变曲线会出现明显的压密阶段;花岗岩的粘聚力随着热处理温度升高而减小,花岗岩的内摩擦角随着热处理温度升高而增加。
In this paper,the granite samples treated by water cooling after high temperature heating are taken as the research object,and the confined pressure test is carried out on the treated granite samples.The test results show that after high temperature treatment,the stress-strain curve of the granite unloaded confining pressure test will appear obvious Compaction stage;the cohesive force of granite decreases with increasing heat treatment temperature,and the internal friction angle of granite increases with increasing heat treatment temperature.
