环渤海滩涂盐渍土路基特征研究

The Characteristics of Saliferous Clay Subgrades in the Bohai Mudflat Area

环渤海地区广泛分布各种类型的盐渍土 ,在沿海道路施工中 ,土中盐类的溶解是造成地基沉陷的主要原因。在综合分析盐渍土地基特征的基础上 ,指出可采用超细水泥固结路基、用高分子材料对路基改性以及采用钢钎维混凝土作路基基础等方法提高路基承载力。

There are various saliferous soils in circum Bohai area In road construction along the sea,the setting of subgrades is induced mainly by dissolution of salt in soils On the basis of comprehensive analysis of the characteristics of saliferous soil bearing capacity,the subgrades can be strengthened by utilizing super fine cement and modified by using high molecular material as well as SFIC in subgrade construction
