Research Progress on the Collapsibility of Saline Soil
The collapsibilityof saline soil can easily lead to problems such as excessive deform-ation 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 col-lapsibility 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 collaps-ibility of saline soil was discussed.
