摘要

讨论了冻土试样的制作过程。采用计算机层析扫描技术(CT)对未饱水和饱水冻土试样单轴压缩过程进行了动态测试

给出了冻土单轴压缩各承载阶段内部微结构变化特征

基于CT测试对加载过程进行了分析

讨论了饱水冻土和未饱水冻土试样的破坏形式

并对空隙损伤阶段损伤进行了计算。

Abstract

The uniaxial compression process of frozen soil was studied by computerized topography (CT) method .The characteristics of microstructure under different loading level are discussed for saturated and unsaturated frozen soil respectively .The feature of failure behavior is given out too .Finally

the damage values resulted from newly born holes and cracks are calculated by using CT distinguishing model .
