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.

Key words: saline soil, coefficients of dissolve settlement, chemical subsurface erosion, three states and two stages
