摘　　要：分散土工程破坏一直广泛存在,针对分散土工程破坏的机理研究仅仅停留在分散土本身的分散机理研究上;因自然环境因素对分散土工程破坏的影响机理和治理措施研究明显不足。本文总结阐述了国内外分散土工程破坏4种不同特征形态,并对4种破坏形态进行机理分析。对当前分散土工程改性和破坏治理现状进行了讨论,指出分散土改性和治理所面对的问题与挑战,为工程建设提供一定参考。The engineering failure of dispersive soil exists widely.The research on the mechanism of engineering failure of dispersive soil only focuses on the dispersion mechanism of dispersive soil itself.The researches on the influence mechanism and treatment measures from natural environmental factors on the dispersive soil engineering failure are insufficient.In this paper,four types of characteristic forms of dispersive soil engineering failure at home and abroad were summarized and their failure mechanism was analyzed.For the engineering modification and failure treatment measures of dispersive soil,the research status was discussed,the problems and challenges were proposed,which could provide a reference for the engineering construction.
