摘    要:温度作用下的裂隙岩体是高放射性核废物的地层深埋处置、地热资源开发以及大都市圈的大深度地下空间开发利用等工程中经常遇到的一类复杂岩体.从加热后裂隙岩体的损伤机理研究入手,通过对不同温度应力作用后大理岩进行单轴压缩试验,得到了各温度下大理岩全应力-应变曲线,并分析了大理岩抗压强度、弹性模量和峰值应变等随加温温度变化的关系及...

关 键 词:裂隙岩体  大理岩  温度应力  损伤机理  单轴压缩试验

Abstract:The heated fractured rock mass is one of the common and complex rock masses encountered in nuclear waste embedment,geothermic exploitation and underground development in big city.Based on the damage mechanism of heated fractured rock mass,the whole stress-strain curves of marble under different temperature are achieved through the marble uniaxial compression tests under different temperature in this paper,and the relations between the marble compression strength,elastic ratio,peak strain and the changes of the temperature are achieved as well as investigating the reason of engendering this phenomenon by analyzing the uniaxial compression tests of marble under different temperature stress.It offers a theoretical base and reference for analysing the mechanical characteristics of rock in high temperature.
Keywords:fractured rock mass  marble  temperature stress  damage mechanism  uniaxial compression test
