摘要
本文介绍了新疆东北部某铁路由于沿线地形地貌、气象特征和地下水特征,形成了铁路沿线特殊的粗颗粒盐渍土条件。通过沿线地表土样进行易溶盐分析的试验数据,分析了沿线粗颗粒盐渍土的粒径特征、盐渍土类型特征、盐渍土含盐量特征和盐渍土的侵蚀性特征。最后依据盐渍土的特征提出了沿线路基工程和桥涵工程的防治对策,为工程建设及附近盐渍土相关工程建设提供一定的参考意义。
This paper introduces the special coarse-grained saline soil condition along a railway in northeast Xinjiang because of its landform, meteorological characteristics and groundwater characteristics. Based on the test data of soluble salt analysis of surface soil samples along the route, the particle size characteristics, type characteristics of saline soil, salinity characteristics of saline soil and erosivity characteristics of saline soil along the route were analyzed. Finally, according to the characteristics of saline soil, the prevention and control measures of roadbed engineering and bridge and culvert engineering along the route are proposed, which provides certain reference significance for engineering construction and nearby saline-soil related engineering construction.
