盐渍土盐冻胀机理及多场耦合模型研究进展
Research Progress on the Mechanism of Frost Heave and Multi-Field Coupled Models of Saline Soil
摘要
Abstract
Under the influence of external environmental factors,the moisture and salts in saline soils undergo repeated crystallization and melting.This periodic physical process continuously disturbs the soil structure,leading to the phenomenon of salt-frost heave,which in turn causes damage to channel linings.Therefore,in-depth research on the mechanism of salt-frost heave in saline soils has become an urgent issue in engineering construction in cold regions.This study reviews relevant domestic and international literature,starting from the research on frost heave in ordinary soils,and summarizes the main research achievements in recent years in two aspects:the salt-frost heave of saline soils and the multi-field coupling models of saline frozen soils.Among them,the multi-field coupling model of saline frozen soils is the focus of this review.The results indicate that the deformation of saline soil is jointly influenced by salts and moisture,and there exists a complex coupling effect between salt heave and frost heave.The multi-field coupling model of saline frozen soil can better explain the mechanism of salt-frost heave and represents a major trend for future development.However,this model is still imperfect and faces challenges such as significant difficulties in obtaining parameters.关键词
