| Abstract:The combination of multiple support methods is more and more widely used in current foundation pit support. For the foundation pit project of No.1516-36 plot in the third phase of Fengtaiyuan east area of Zhongguancun Science and Technology Park, Fengtai District, Beijing, the pile anchor is selected for overall support in combination with soil nailing wall plus large rate sloping, large sloping anchor spraying plus cantilever piles for local support according to the actual requirements. The third-party monitoring results of the foundation pit by the relevant surveying and mapping units are all within the safe deformation range, meeting the design requirements. |
