摘要/Abstract

摘要： 对常温至800℃热作用后大理岩波动特征及单轴压缩过程中的声发射特性和损伤演化进行研究，结果表明:高温后大理岩体积变大，质量与密度减小，600℃是质量与密度变化的阈值温度；随温度升高，峰值应力和弹性模量先增大后减小，峰值应变单调增加，纵波与横波波速呈线性下降，频谱面积、主频幅值和振幅下降，但下降速率逐渐减小；声发射振铃计数与应力-应变曲线有较好的对应关系，能够反映大理岩不同阶段的损伤演化规律；高温使大理岩由突发性破坏向渐进性破坏发展，破坏模式由剪切破坏向劈裂破坏转变.

关键词: 高温；大理岩；波动特征；声发射；破坏形态；微观结构

Abstract: The wave and acoustic emission characteristics，as well as the damage evolutions of marble from room temperature to 800℃ under uniaxial loading were studied. The results show that for heated marble， the volume increases and the mass and density decrease. 600℃ is the threshold temperature for mass and density changes. With the increase of temperature， the peak stress and elastic modulus initially increase then decrease， while the peak strain increases monotonically. With the increase of temperature， the P-wave and S-wave velocity decreases linearly， while the spectrum area， main frequency amplitude and amplitude decrease with a decreased decline rate. It is also found that there exists good consistence between the accumulated AE accounts and the stress-strain curve， which fully reflects the damage evolution law of marble in different stages. Under the effect of high temperature， the failure of marble specimen change from brittle failure to progressive failure， and the failure modes change from shear failure to splitting failure.

Key words: high temperature; marble; wave characteristics; acoustic emission; failure mode; microstructure
