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 a possibility for non-destructive continuous detection and quantitative description of the internal structure of specimens under different experimental conditions. In this paper, the change of structure during the creep of frozen soils is observed and analyzed by this method. It is considered that the creep of frozen soils The development of micro-cracks, the destruction of particle aggregates and the proliferation and expansion of other structural defects restrict the strengthening and weakening of soil structure, control the morphological characteristics of creep process, and also give the CT value and material density And water content of the quantitative relationship between.
