摘要
以新建锡北铁路盐湖区路基为研究对象，通过控制路基填料中氯离子、硫酸根离子含量来满足设计规范要求，详细介绍了卤水喷洒砂性土填筑路基的新型施工技术，并针对此技术填筑的路基进行病害分析，采取了相应的整治措施，解决了高寒盐湖地区砂性土填筑路基施工淡水缺乏、填料水分散失快、压实困难、机械设备功效低等难题。
In this paper,taking the newly-built Xibei Railway subgrade in the salt lake area as the research object,we controlled the content of chloride ion,sulfate ion in subgrade filling to meet the design specification requirements,and fully discussed the new construction technology named the brine spray sand soil filling roadbed,and analyzed the filling roadbed disease,then adopted corresponding improvement measures to solve problems of fresh water shortage,filling water loss fast, compaction difficult,low efficiency of mechanical equipment and so on.
