建筑工程基坑支护设计

Design of Foundation Pit support for Construction Projects

为保证基坑开挖稳定性,文章以某大型商业建筑的深基坑为研究对象,分析了支护设计原则,利用专家咨询法对不同支护方案进行对比,最终选定了“钻孔灌注桩+锚杆”支护方案。随后,采用Midas/GTS软件建立基坑计算三维模型,分析基坑在不同工况下的变形,以验证支护方案的可行性,研究成果可为类似基坑设计提供理论指导。

In order to ensure the stability of foundation pit excavation,this paper takes the deep foundation pit of a large commercial building as the research object,analyzes the support design principles,compares different support schemes by using expert consultation method,and finally selects the"bored pile+bolt"support scheme.Subsequently,the three-dimensional model of the foundation pit was established by Midas/GTS software,and the deformation of the foundation pit under different working conditions was analyzed to verify the feasibility of the support scheme,and the research results could provide theoretical guidance for the design of similar foundation pit projects.
