闹市区某深基坑工程支护方案设计与施工

Design and Construction of Supporting Scheme of a Deep Foundation Pit in Crowded Downtown

以城市闹市区的一深基坑工程支护设计和施工为例,采用钻孔灌注桩作为挡土结构,坑内设置钢筋混凝土内支撑,采用锚杆进行支护。通过对支护方案的选择和检测进行分析,得出了一些有价值的结论,可为类似的基坑工程的支护设计提供经验。

The example of design and construction of support for a deep foundation pit in crowded downtown is given in this paper. In this deep foundation pit, the bored cast-in-place piles are used as the retaining structure. In addition, the internal rein forced concrete support and the blot are also used in this pit. Some useful conclusions were drawn through the analysis of selection and detection of supporting scheme. This can be helpful for the support design of similar foundation pits.
