摘　　要：为了提高盐田底板盐渍土土层的防渗性及强度性能,根据盐渍土的物理化学性质,结合工程实例,采用盐化处理和盐化处理+碾压两种方法进行处理.现场原位渗透实验和室内物理力学实验结果表明:处理后盐渍土的防渗性和土层的承载力得到了明显改善,两种方案均能满足工程设计要求.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.
