| 摘 要： | 将盐渍土化学潜蚀溶陷变形过程划分为3状态2阶段进行分析,并根据阶段变化规律总结出不同状态时土体物理指标间的相互关系.通过该关系分析出盐渍土溶陷发生的关键阶段,并推导了盐渍土溶陷系数与溶陷前后土体物理指标间的数量关系.分析并验证了土体的孔隙比、含盐率以及土体的结构组成形式都是影响盐渍土潜蚀溶陷变形的重要因素.

| Abstract: | The process of the chemical subsurface erosion dissolve settlement of the saline soil is divided into three states and two stages; of and the interrelation of the physical parameters of saline soils is summarized. Through analyzing this relationship, the key stage which the dissolve settlement happened is known. The quantitative relations about the coefficients of the saline soil's dissolve settlement and the soil's physical parameter are derived. The result is that the void ratio, the salt quality, the form of the soil structure are important factors effecting the dissolve settlement of saline soils. |
