摘要
以新疆奎屯某道路改造工程为例,通过试验方法确定项目路段属于中硫酸盐渍土,水盐运移上升最大高度为770mm,并通过对比,结合原有公路基础,设计采用“土工布隔离层法+换填法”来处理盐渍土路基,取得了很好的治理效果。
Taking a road reconstruction project in Kuitun,Xinjiang as an example,this paper determines that the project road section belongs to medium sulfuric acid saline soil by test method,and the maximum height of water and salt migration rise is 770mm.Through comparison,combined with the original road foundation,the design adopts"geotextile isolation layer method+replacement method"to deal with the saline soil subgrade,which has achieved good governance effect.
