粗颗粒盐渍土在我国新疆地区分布广泛,由于其特殊的溶陷、盐胀等特性,在工程建设中需进行处理。选取新疆准东地区某电厂厂区内粗颗粒盐渍土样,掺合一定配比的水泥、消石灰、粉煤灰对其进行化学改良试验,结果表明:掺合一定比例的水泥、粉煤灰、消石灰均可对粗颗粒盐渍土溶陷性进行消除,且三种掺合料混合配比改良效果优于单一掺合料改良。
Coarse-grained saline soil is widely distributed in Xinjiang of China. Due to its special characteristics such as dissolution and salt expansion, it needs to be dealt with in the project construction. The coarse grain salty soil sample in a power plant in the eastern part of Xinjiang Autonomous Region was selected and chemically modified with a certain proportion of cement, hydrated lime and fly ash. The results show that: when a certain proportion of cement, fly ash, Lime can reduce the solubility of coarse-grained saline soils, and the effect of improving the mixing ratio of the three admixtures is better than that of the single admixture.
