摘要
ＣＴ为非破坏的持续检测和定量描述不同实验条件下试样的内部结构提供了可能，本文利用这一手段观测分析了冻土蠕变过程中结构的变化增况，认为冻土蠕变过程中所进行的发育微裂隙、颗粒集合体的破坏以及其它结构缺陷的增生与扩展，制约着土结构的强化与弱化作用，控制着蠕变过程的形态特征，同时还给出了ＣＴ值与物质密度和含水量之间的定量关系。
CT provides possibilities for both continuous undamaged meaurement and quantative description of internal structure of sample under different experimental conditions. In this paper, CT is used to measure and analyze the change of structure of frozen soil in creep process. It is considered that the strengthening and softening action of structure of frozen soil are controlled by growing microcracks,being broken particle aggregates and growing and extending structural damage in creep process, as well as the form characteristics of creep process.Meanwhile,the relationship among CT value, density and water content is given.
