摘　　要：盐渍土的溶陷特性极易导致道路工程出现变形过大等问题,而盐渍土地区工程建设中盐渍土利用率的提高,不仅可以减少因弃用所致的生态破坏,而且可以就地取材节约资源、降低成本,因此,研究盐渍土的溶陷特性及其工程应用至关重要。鉴于此,系统地总结了盐渍土溶陷性研究的室内试验和现场试验方法,对比分析了各种试验方法的特点及适用范围。从研究对象出发,阐述了细粒盐渍土、粗粒盐渍土及改良盐渍土溶陷特性的研究现状,梳理了试验结果的现有分析手段,探讨了盐渍土溶陷性研究的发展方向。The collapsibilityof saline soil can easily lead to problems such as excessive deformation in road engineering.The improvement of the utilization rate of saline soil in the construction of saline soil areas can not only reduce ecological damage caused by its abandonment,but also save resources and reduce costs by using local materials.Therefore,it is crucial to study the collapsibility and engineering applications of saline soil.In view of this,the indoor and on-site test methods for studying thecollapsibility of saline soil were systematically summarized,and the characteristics and applicability of each test method were compared and analyzed.Starting from the research object,the current research status of the collapsibilityof fine-grained saline soil,coarse-grained saline soil and improved saline soil was introduced.Existing analytical methods for experimental data were sorted out.Finally,the development direction of research on the collapsibility of saline soil was discussed.
