泡沫轻质土在盐渍化软土地区桥头路基的应用研究

从桥头跳车现象产生原因分析泡沫轻质土修筑桥头过渡段减少桥头跳车现象的可行性.以典型的盐渍化软土地区—天津滨海新区轻纺经济区的道路工程为例,分析轻纺经济区的地质、含盐量;对采用泡沫轻质土的路基处理结构进行室内回弹模量以及CBR测试,结果表明,泡沫轻质土均能满足路基相关规范对路床范围内的要求.

Applied Research on Foam Light Soil Salination Soft Soil Area Bridgehead Roadbed

From phenomenon of bump at bridge - head causing by analysis of building bridgehead transition section with foam light soil and reducing the possibility of phenomenon of bump at bridge - head. Taking typical salination soft soil area - road engineering of Binhai New Area Textile Economic Zone of Tianjin as an example, analyzing geology, saltiness in Textile Economic Zone; subgrad indoor rebound modulus and CBR test, the results show that e treatment structure adopted by foam light soil for foam light soil can meet relevant specification of subgrade against the requirement within the scope of roadbed.
