分散性黏土研究现状与展望

分散性黏土抗水蚀能力很低,对水利工程、道路工程等建筑物的安全性造成严重威胁,是近年来岩土工程界比较关注的特殊土类之一。由于分散性黏土发现较晚,工程实例较少,对分散性黏土的研究不够深入。文中从发现历史与工程危害、地质条件与分布规律、试验鉴别方法与工程特性、分散机制与微观结构、工程应用等方面对分散性黏土的研究现状进行了分析总结,提出研究中存在的若干问题及研究方向。

Current researches and prospects of dispersive clay

Dispersive clay has the very low erosion resistance capacity so as to cause serious threatening to the engineering safety such as the hydraulic engineering and road engineering. It is one of the problematic soils which have been concerned in the geotechnical engineering field. As dispersive clay was found later and engineering cases were less, those studies of dispersive clay are still not deep enough. This paper has analyzed and summarized the current researches from some sides, such as the discovery history and the engineering hazards, the geological condition and the distribution rules, the identification methods, the engineering properties, the dispersive mechanism and the microstructure and the application. Some issues in the researches and the direction of researches are pointed out.
