【摘要】 重点简述中国近20a在高温作用下和高温作用后岩石力学特性研究所取得的成果。国内学者在高温作用下和高温作用后岩石的单轴压缩试验已开展了大量的研究,而开展高温作用下岩石的拉伸断裂试验和蠕变试验等相对偏少。国内学者主要基于统计损伤力学建立了高温下和高温后岩石的力学模型,但有些模型还存在不足,并未通过实际工程进行验证模型是否适用。更多还原

【Abstract】 This article give a brief of the progress in study on mechanical properties of rock under high temperature and after high temperature for nearly 20 years in China.Lots of Chinese scholars had conducted uniaxial compression tests of rock under high temperature and after high temperature.However,tensile rupture test and creep test of rock under high temperature had relatively less been carried out.Lots of scholars had established constitutive models for rock under high temperature and after high temperature mainly on base of statistical damage mechanics.These constitutive model are still imperfect,and the applicability had not been verified in actual engineering.更多还原
