摘要
为较好地解决淤泥质软土场地施工时大直径随钻跟管桩钻进设备容易下陷的技术难题,从施工的安全性和效率方面考虑,研究提出了一种支撑力强、构造简单、可重复利用、成本低的软土施工用船筏式钢箱梁浮桥,并对船筏式钢箱梁结构的设计方案、预期经济效益和应用前景进行了分析。本文研究方法和思路可为其它大型设备在软弱地基的安全施工提供借鉴。
In order to better solve the technical problem which the equipment of Drilling with Large Diameter Rock-socketed PHC Pipe Cased Pile is easy to sink in the construction of silt soft soil site. Taking into account the safety and efficiency of construction, a ship design method of steel box pontoon bridge is researched, which have strong support, reusability and low-cost construction, and used in soft soil construction. The paper analyzes the design scheme of ship raft steel box girder, its expecting economic benefits and application prospects. The research methods and ideas can provide reference for the safety construction of other large equipment in soft foundation.
