Experimental Analysis of Properties of Saline Soil Improved by Cement Under Freezing and Thawing Conditions
In order to improve the quality of highway construction in saline soil area,the freeze-heave ratio,unconfined compressive strength and grain size composition of improved saline soil under freeze-thaw conditions were analyzed experimentally from the aspects of cement content,salt content and maintenance measures.The results show that with the increase of cement content,the frost heave rate of improved saline soil decreases,the content of powder and grain increases,and the unconfined compressive strength increases.The unconfined compressive strength of modified saline soil decreases with the increase of salt content.
