摘要
软土路基是我国乃至全世界常见的一种特殊路基,多分布于江、河、海洋沿岸、内陆湖泊、塘、盆地和多雨的山间洼地。软土具有含水量大、渗透性差、天然强度低和压缩性高等特征。结合某高速公路软土路基差异沉降实例,分析病害发生的原因,提出以水泥搅拌桩、反压护道、固结排水的综合处理方案。
Soft soil subgrade is a kind of special subgrade co mmon in China and even the whole world,which is mainly distributed in rivers,rivers,coastal areas,inland lakes,ponds,basins and rainy mountain depressions.Soft soil has the characteristics of large water content,poor permeability,low natural strength and high compressibility.Based on an example of differential settlement of soft soil subgrade of a highway,the causes of the disease are analyzed,and a comprehensive treatment scheme of cement mixing pile,back pressure protecting road and consolidation drainage is proposed.
