摘要
以上海某超大型深基坑工程为背景,详细介绍了软土地区中心岛支撑方案的概况和施工工艺流程,并对实施过程中的关键节点和技术进行具体论述,为类似工程积累了宝贵的经验。该项目通过采用中心岛法的基坑支护方式,有效地利用了新建建筑结构作为基坑加固的一部分,降低了基坑加固成本,缩短了施工工期。并且由于整个加固施工过程均可视,使基坑支护结构安全处于受控状态,取得了良好的工程效益。
Based on a very large deep excavation in Shanghai, this article provides a detailed introduction of design, construction technology and process of the central island retaining system in soft soils. The paper specifically discusses the key issues and solutions of the design-construction process of the retaining system. The introduction provides a valuable design/construction experience for the similar projects.
