Abstract

The salt and frost heaving damage of soil in the saline soil area seriously endangers the stability and durability of pipelines,highways,railways,airport runways,bridges and other engineering buildings.Therefore,it is very important meaning to solve the problems of salt and frost heaving in actual engineering.In this paper,the latest research results on the mechanism of salt frost heaving in recent years are reviewed from the aspects of microstructure,single cooling,freeze-thaw cycle,water-salt migration and construction mechanism model.The problems and shortcomings in the current research are summarized,and the research direction of salt freezing and swelling mechanism of saline soil is prospected.
