上海地区新建试车场软土路基加固与沉降观测实例分析

Monitoring and analysis of settlement of strengthened softground subgrade in Shanghai

上海市大众汽车公司新建试车场,部分专用路基高达6～14 m,出于测试汽车性能的需要,对路基的工后沉降提出了高标准的要求。设计和施工单位做了一系列的试验和探索,既有成功的经验,也有不成功的实例。取得的经验教训对于今后在上海地区软土地基上构筑高标准的高填路基(如高速铁路等)有参考价值。

In Shanghai Volkswagen Automobile Testing Yard, a lot of subgrades 6~14m are embanked on the softground. Different methods to strengthen the soft soil are adopted in order to reduce settlement as small as possible. Records from field practice may be useful to engineers for making highway or railway softground subgrades in Shanghai area.
