高温花岗岩遇水快速冷却后力学性质实验研究
|
摘要
通过对高温加热–遇水快速冷却后的花岗岩试样进行单轴和三轴实验,研究了800℃内高温花岗岩遇水快速冷却后的力学性质随温度和围压的变化规律。实验结果表明:(1) 400℃为高温加热–遇水快速冷却对花岗岩力学性质影响的阈值;(2)同一温度条件下,峰值偏应力、峰值应变随围压的增大而增大;弹性模量随围压的增大先增大后减小;(3)单轴实验中,温度低于400℃时,岩样表现为复合破坏,随着温度的升高破坏形式转变为拉破坏;三轴实验中,岩样整体上表现为剪切破坏。
With the uniaxial and triaxial compression tests of the water-cooled granite samples under high temperature, the mechanical properties of the water-cooled granite under high temperature within800 ℃ against the temperature change and the confining pressure are determined. The experimental results indicate that:(1) The threshold for the effect of high temperature heating and rapid cooling with water on the mechanical properties of the granite is 400 ℃.(2) Under the same temperature condition, the peak deviator stress and the peak strain increase with the increase of the confining pressure. The elastic modulus increases first and then decreases with the increase of the confining pressure.(3) In uniaxial tests,when the temperature is lower than 400 ℃, the rock samples will be in a form of composite failure. With the increase of the temperature, the damage morphology changes to a tensile failure. While in the triaxial test, the rock samples all have the shear failure.
