Research progress on engineering characteristics and solidification techniques of saline-alkali soils
This paper provides an overview of the current research status on the physical,chemical,and engineering characteristics of saline-alkali soils,focusing on issues such as dilatation,collapsibility,and freeze-thaw damage in the soil materials of saline-alkali soil regions.To mitigate the adverse effects of sa-line-alkali soils on engineering projects,common stabilization methods are summarized and their respec-tive solidification mechanisms are analyzed.Furthermore,this paper reviews the physical and mechanical properties of saline-alkali soils after solidification through various approaches,particularly in cold regions.The prospects for the future development of solidifying saline-alkali soils are discussed,along with poten-tial directions for engineering research in this field.
