摘　　要：针对盐渍土泥沼地带路基所出现的局部沉陷、膨胀、翻浆严重,以及大面积长时间整体沉陷、变形等病害,笔者从盐渍土泥沼的特性入手,结合《公路路基设计规范》(JTGD 30-2004),从路基的设计原则,盐沼换填方案,换填工艺施工,边坡防护,路基排水等方面,提出了比较合理的盐渍土泥沼地带路基的治理措施和方法.In this paper, logical treating measure and method are proposed against failings in salty soil swamp area such as part settlement, expansion, frothing, long- time widely entire settlement, deforming, etc. The research start with the characteristic of salty soil swamp together with Handbook of Subgrade Designing in Highway Engineering（JTG D30 -2004）. The conclusion is given from several points including subgrade designing principle, replacement project in salina, replacement technology, slope protection and subgrade drainage.
