在室内实验条件下,改变氯盐渍土的含水量、含盐量及压实密度等物性参数,分析了土体抗剪强度τ随土体含水量与含盐量比值m及土体干密度ρd的变化关系。结果表明氯盐渍土抗剪强度τ的变化以含盐量约为8%分界。当比值m≤1.5时,τ随m的增大而减小;当比值m≥1.5时,τ随m的增大有较明显的线性上升趋势。 Under laboratory conditions, the physical and chemical parameters such as water content, salt content and compaction density of chlorinated saline soils were changed. The relationship between shear strength τ of soil and ratio of soil water content to salinity m and soil dry density ρd changes in the relationship. The results show that the change of the shear strength τ of the saline soil is divided by the salt content of about 8%. When the ratio m≤1.5, τ decreases with the increase of m. When the ratio m≥1.5, τ increases linearly with the increase of m.
