高温下花岗岩基本力学性质初步研究

A preliminary study on basic mechanical properties for granite at high temperature

摘要: 通过试验 ,初步研究了花岗岩在单轴压缩 ( 2 0～ 6 0 0℃ )状态下主要力学参数随温度的变化规律。指出了 75℃、2 0 0℃分别是花岗岩弹性模量和单轴抗压强度的门槛温度。

Abstract: By means of a large number of experiments,main mechanical properties under uniaxial compression(20～600 ℃) are preliminarily studied.It is pointed that 75℃ and 200℃ are the threshold temperatures of elastic modulus and uniaxial compression strength respectively.
