摘　　要：新疆南部地区土壤盐渍化现象普遍存在,盐渍土对高速公路的建设和使用产生了很大的影响。G314线库阿高速公路土壤盐渍化较为严重。通过对该线路沿线土壤进行调查与取样分析,详细查明了盐渍土的形成原因主要是该地区特殊的气候、地形地貌、水文地质和地层岩性特征等条件共同作用的结果;并对盐渍土的性质、盐渍化程度、土壤类别、液塑限、最优含水率和最大干密度等进行了系统地分析,为公路路基的盐渍土病害防治提供了科学依据。Soil salinization phenomenon is widespread in south of Xinjiang, saline soil had a great highway construction and use. Soil salinization of G314-line ku-A highway is more serious. Through impact on the the saline soil investigation and sample analysis of the line, identified is detailed. The region＇s special climate, topography and geomorphy, hydrogeological and formation lithological condition＇s common effect are the main reason for the formation of saline soil, and systematically analyzed saline soil properties, degree of salinity, soil types, liquid and plastic limits, optimum moisture content and maximum dry density etc, and provide a scientific basis for saline soil disease prevention of highway subgrade.
