| 摘 要： | 以探讨超氯盐渍土的含盐量与工程特性指标间关系为目的 ,采用室内土工试验与数学分析相结合的方法 ,深入研究了含盐量对塑性指标、抗剪强度的影响以及盐渍土渗透系数与干重度、含水量之间的关系。研究发现 :超氯盐渍土洗盐前后可塑性变化幅度较大 ;抗剪强度随含盐量增加而增大 ;在干重度、含水量与渗透系数三者相互关系中存在界限含水量和界限干重度。所得结论对深入研究盐渍土的工程特性、指导盐田建设将有所裨益

| Abstract: | In order to probe into the relationship between salt content of ultracholrine saline soil and the engineering property indexes, we use the combined method of erperimental testing with mathematical analysis. It is discussed here that the effect of salt content on plasticity index, shear strength and the relationship among the coefficient of permeability, dry density and water content. The results declare that ultracholrine saline soil has bigger variations of plasticity before and after washing salt; its shear strength increases with the raising of salt content; there exists limited water content and limited dry density in the relations among coefficient of permeability, dry density and water content. This study makes benefit for the further research on engineering property of saline soil and the construction of salt field. |
