摘要
本文讨论了硫酸盐渍土盐胀率随含水量、硫酸钠含量、初始干容重、温度和Cl-/SO42-五因素变化的规律.指出了含盐量、含水量、初始密度对盐胀影响程度不同且具有交互作用.通过分析Cl-/SO42-对硫酸盐渍土盐胀的抑制规律,介绍了灌注氯化钙抑制盐胀的方法,为硫酸盐渍土地区的公路路基处理提供参考.
In this paper, the author analyzed the laws of salt heaving rate which vary with five factors including water content, Na2SO4 content, initial dry density, temperature and Cl^-/SO4^2-. It is pointed out that The salt content, water content and initial dry density have different influence degrees to salt heaving, also, there is cross function among them. Introduced the method of restrain salt heaving by injecting CaCl2, it can be referenced in sulphate salty soil areas.
