ＣＴ为岩土材料非破坏的持续检测和内部结构的定量描述提供了可能，利用这一手段观测分析了冻土单轴蠕变过程中结构的变化情况，结果表明蠕变过程中结构缺陷的增生与扩展制约着土的结构的强化与弱化作用，控制着蠕变过程形态特征。易破坏区首先发生于样品的低密段，在软弱段的某一薄弱层面形成一环状低密带，然后向外扩展，最终导致整体结构的破坏 CT is a non-destructive continuous detection of geomaterials and a quantitative description of the internal structure. This method is used to observe and analyze the structural changes during the uniaxial creep of frozen soils. The results show that the structural defects in the creep process are hyperplastic With the expansion of the constraints of the strengthening and weakening of the role of soil structure, control the morphological characteristics of the creep process. Vulnerable regions first occur in the low-density sections of the sample, forming an annular low-density band at a weakened level of the weak section and then expanding outward, eventually causing damage to the overall structure
