| 摘 要： | 介绍了虹桥商务区8号地块的结构设计难点及关键技术应用,重点阐述"桩墙合一"技术、软土地区扩底桩以及大悬挑结构的设计方法。"桩墙合一"技术把围护排桩与地下室外墙作为共同的抗侧力结构,可较好地利用排桩这种临时支护体系;扩底桩可有效地提高桩的承载能力。对于近年工程中频繁出现的大悬挑结构,结合本工程提出了设计分析的整体思路及施工措施。

| Abstract: | The structural design difficulties and the applications of key technology were described,especially focused on the design method of pile wall interaction,base-enlarged pile in soft soil area and large cantilever structure.To take retaining pile and basement wall as a common resist lateral force structure,pile wall interaction technology can be a good use of the retaining pile of temporary support system;base-enlarged pile can effectively increase the bearing capacity.In recent years,there are many large cantilever structures,and combined with this project,the trains of thought and construction measure for similar structure were provided. |
