摘要： 膨胀土裂隙特征作为裂隙研究的基础，对膨胀土边坡稳定性研究有着重要的意义。裂隙的观察和提取是一个复杂的过程，目前的裂隙特征研究虽然取得了一些进展，但尚未获得广泛认同的关键成果，定性和定量化的描述裂隙的发展能够进一步了解膨胀土的性质。探讨了膨胀土微观量测方法的发展历程和现状，总结归纳了目前常用的微观量测方法。（1）目前定量分析虽然有许多，但是主要还是定性分析，量化指标和体系有待健全，并且微观结构和力学间的关系还需完善；（2）介绍了膨胀土裂隙形成的影响因素；（3）总结归纳了膨胀土裂隙微观结构的直接观测方法、间接观测方法和统计分析方法。

Abstract: The research on the fracture characteristics of the expansive soil is the foundation of the fracture research. Qualitative and quantitative description of the development of fissures can further understand the properties of expansive soil. The development and present situation of micro measurement methods of expansive soil are discussed, and the commonly used micro measurement methods are summarized. The conclusions are as follows: (1) Although there are many quantitative analyses, it is mainly qualitative analysis, quantitative index and system need to be improved and the relationship between microstructure and mechanics needs to be improved. (2) The influencing factors of the formation of the cracks in expansive soil are introduced. (3) The direct observation method, the indirect observation method and the statistical analysis method about the fracture microstructure of the expansive soil are summarized.

Key words: Expansive Soils, Fracture, Micro Measurement Methods, Image Processing, Research Progress
