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。
Various types of saline soil are widely distributed in the Bohai Rim. In the coastal road construction, dissolution of salts in the soil is the main cause of foundation settlement. Based on the comprehensive analysis of the characteristics of saline soil foundation, it is pointed out that the bearing capacity of subgrade can be improved by using ultra-fine cement to consolidate the roadbed, modifying the roadbed with polymer materials and using steel fiber reinforced concrete as subgrade.
