Treatments of dynamic displacement and Gravel material column have been applied in Charhan salt lake area. In order to master the settlement character of high-saline to excessive-saline weak ground which has been treated, Ground settlement has been monitoring. Results of settlement monitoring analysis may guide others' projects and fill the .technology void of highway construction in saline soil regions.%察尔汗盐湖地区高速公路盐渍化软土地基主要采用强夯置换和砾石桩等方法处理,为摸清强～过盐渍土地区高速公路复合地基的沉降变形规律,对处治后的地基进行了地表沉降监测.监测分析成果对工程实践有重要的指导作用,填补了高速公路在盐渍土地区试验工程的空白,为盐渍化软土地基监测积累经验.
