摘　　要：随着城市化进程的加快,深基坑工程在城市建设中日益增多,对基坑围护结构的强度和抗渗性能提出了更高的要求。本文以SMW工法桩作为研究对象,并以雄安新区京雄快线项目一标段航站楼站为载体,深入探讨了其作为深基坑围护结构的优势与特性。通过理论分析与实验验证,表明SMW工法桩能有效隔绝基坑内外的水系联系,确保基坑开挖及主体结构施工能在无水环境下进行,同时插入的型钢能显著增强工法桩的强度,有效防止基坑在边坡荷载作用下发生变形或破坏。本文的研究结果对于提升深基坑工程的安全性和稳定性具有重要的理论意义和应用价值。With the acceleration of urbanization process,the number of deep excavation projects is increasing in urban construction,which puts forward higher requirements for the strength and anti-seepage performance of excavation retaining structures.This article takes the SMW piles as the research object,and uses the terminal station of the first section of the Beijing-Xiong’an Express Line project in Xiong’an New Area as the carrier to deeply explore its advantages and characteristics as a deep f excavation enclosure structure.Through theoretical analysis and experimental verification,it has been shown that SMW piles can effectively isolate the water system connection inside and outside the foundation pit,ensuring that excavation and main structure construction can be carried out in a water-free environment.At the same time,the inserted steel sections can significantly enhance the strength of the piles and effectively prevent deformation or damage of the foundation pit under the action of slope load.The research results of this article have important theoretical significance and practical value for improving the safety and stability of deep foundation pit engineering.
