不同初始损伤白砂岩高温处理后的力学性能研究
Study on mechanical property of white sandstone with different initial damages after treatment of high temperature
摘要
Abstract
Through the mechanical test of white sandstone with various degrees of initial damage after treatment of different high temperatures,the paper analyzed the influence of different target temperatures and initial damage on elastic modulus,peak stress and microscopic structure.The results show that elastic modulus and compressive strength of white sandstone affected by initial damage decrease with the increase of temperature.The greater the initial damage,the severer the impact of high temperature on white sandstone.Through the observation by using microscope,the crystal of specimen becomes smaller and incomplete,cuttings is more.In addition,the paper set up the stress-strain curves of white sandstone with different initial damages and temperatures.关键词
