摘要

对河南省某地产25块花岗岩样品进行高温预热处理，测量了加温前后弹性纵波波速，并对样品进行单轴压缩应力-应变全过程试验。通过以上试验，给出如下结果：温度对岩石损伤变化的作用；温度对岩石裂隙密度和损伤应变能释放率的影响。实验结果验证了花岗岩的塑性应变主要与偏斜应力产生的形状改变比能有关，而与体积改变比能的关系不大。

Abstract

The compressional elastic wave velocities are measured for 25 granite samples in Henan Province before and after high temperature; and the complete stress and strain experiment of uniaxial compression is carried out. Through the experiment

the rock damage change due to temperature

temperature affects on rock porosity density and damage strain energy release rate

were observed. The experimental data show that the plastic strain of granite mainly depends on the strain energy of distortion due to deviatoric stress

but not on the strain energy of volume change.
