摘要
以南京德基广场二期项目为背景,介绍了裙楼上下同步逆作与主楼顺作相结合的深基坑支护设计与实践,总结了裙楼上下同步逆作与主楼顺作相结合的关键技术与对策。实施与监测结果表明,裙楼上下同步逆作与主楼顺作相结合大大加快了裙楼的施工进度,实现了既定建设目标,整个实施过程有效的保护了周边环境,节约了社会资源,取得了良好的社会效益,可为类似工程提供借鉴和参考。
Based on the second phase project of Nanjing Deji square, this paper introduces the design and practice of deep foundation pit engineering combining the top-down method for the annex building and ordinary excavation method for main building, and summarizes the key technologies and countermeasures of the combination of the top-down method for the annex building and ordinary excavation method for main building. The results monitoring show that the combination of the top-down method and ordinary excavation method greatly accelerates the construction progress of the annex building, achieves the established construction goal, effectively protects the surrounding environment, saves social resources, and achieves good social benefits, which can provide reference for similar projects.
