Abstract: Based on the physical and chemical properties of saline soil, a method of salinization treatment and a combined method of salinization treatment with RCC were used to improve the anti-permeability and strength property of saline soil located in the bottom of salt field. The results of in-situ permeability testing and indoor physical-mechanical testing show that the anti-permeability and strength property of saline soil after treatment have been markedly improved. All the two measures can meet the requirements of project design.
