摘要

对经历不同温度后盐岩的力学性能进行了试验研究，分析了盐岩应力-应变曲线、峰值应力、峰值应变、弹性模量等的变化情况。分析结果表明，温度对盐岩的物理力学特性影响较大，随着温度的升高，盐岩的力学性能劣化明显，峰值应力和弹性模量降低，峰值应变增加；峰值应力可以表示成围压与温度的函数，并从盐岩弹性模量随温度的变化规律入手，导出了热损伤演化方程和一维TM耦合损伤本构方程。

Abstract

Testing studies is made on the mechanical properties of rock salt after undergoing different high temperatures

The mechanical properties include stress–strain curve

peak stress

peak strain

modulus of elasticity. the results indicate that the temperatures is obviously affect the mechanical properties of rock salt

the mechanical properties deteriorate rapidly along with the increase of temperatures

the peak stress and modulus of elasticity decrease rapidly

the peak strain increase rapidly. The peak stress is a power function of confining pressures and temperatures. Based on the relation of elastic modulus and temperatures for rock salt

the thermal damage evolution and one dimensional TM coupled damage constitutive equation are established
