摘要拟建中的中国工商银行苏州分行大楼位于苏州工业园区南施街与旺墩路交叉口西北角，西侧及北侧均为河道（未修筑驳岸），地处苏州工业园区金融区。本工程建（构）筑物包括1幢22层（局部15层）主楼（设有3层地下室）、和主楼北侧的4~5层裙房（3层地下室）及与其相通的外扩3层外扩纯地下室组成。基坑面积约为20000m2，周长约为580m。52538
结合本工程地质、环境、挖深等诸多因素，由此分成两段确定安全可靠的支护方案；为基坑土方开挖和地下室施工创造一个安全干燥的施工环境；基坑采用深层搅拌桩止水，排水沟排水。土层锚杆作为一种较新的工程技术，将会更广泛地运用到工程实践中，其具有较高的科学性、使用性，且施工方便，不占场地。根据周边情况和土层信息的不同，北侧和西侧为河道，南面和东面为道路，所以分成两个不同的截面进行计算。
设计的主要内容有支护方案的选择、钻孔灌注桩的设计与计算、土钉及锚杆的计算、基坑的止水和施工组织设计。
毕业论文关键词：深基坑支护；钻孔灌注桩；深层搅拌桩；锚杆支撑；施工组织设计。
Abstract The Industrial and Commercial Bank of China Suzhou branch building located in the Suzhou Industrial Park, in the Northwest at the crossing of Nancy Street Northwest and Wang Dun Road, in the West and north side are River (not built waterfront), located in the Financial District of Suzhou industrial park. The engineering construction including 1 buildings with 22 layer (15 layer in part with 3 basement), 4~5 layer and building on the north side of the podium (3 basement) and communicated with the outside the extended 3 layer outside the expansion of pure basement. Excavation area is about 20000m2, length is about 580m.
Combined with the engineering geology, environment, dig deep factors determine safe and reliable supporting scheme, to create a safe environment for the construction of dry construction of foundation pit excavation and foundation pit. Using the deep mixing pile, drainage ditch drainage. Soil anchor is a new science, will be more widely applied to engineering practice, its scientific nature, has high usability, and construction is convenient, does not occupy space.
The design of the main contents are supporting scheme selection, design and calculation of bored pile, soil nailing and anchor calculation, foundation pit stop and construction organization design.
Key words: deep foundation pit; bored pile; deep mixing pile; anchor support; construction organization design.
