邻近建筑物的深基坑工程实例

An Example of Deep Foundation Pit Engineering with Adjacent Buildings

摘要:

沈阳华晨宝马新工厂主办公楼工程周边有邻近建筑物，其深基坑工程为坑中坑形式，基坑开挖深度为10.4 m，局部开挖深度6.05、7.4 m。为了控制变形，采用排桩+旋喷桩止水帷幕作为挡土结构及坑内管井降水方式。通过对支护方案的选择和现场施工结果的分析，为基坑周边存在邻近建筑物、基坑上部存在独立基础的基坑支护的设计与施工提供一定的参考。

Abstract:

In the foundation pit engineering for an office building of BMW Brilliance in Shenyang, the excavation was pit in the foundation pit with depth of 10.4m and local excavation depth 6.05 to 7.4m, and the adjacent buildings surrounding around. Row piles and rotary jet grouting pile water-stop curtain were adopted as retaining structure and dewatering method to control the deformation. The selection of supporting scheme and the analysis on the construction effects could be the reference to the design and construction of the similar project.
