This paper describes the excavation process of foundation pit excavation of Dongyang Station,part of the Phase Ⅱ project of Shijiazhuang urban rail Transit Line 1.To ensure stability during excavation,a combination of φ800@1200 bored piles and triple steel struts was used as the support system.The foundation pit excavation the top-down method,with layers and sections excavated sequentially while implementing support measures immediately after excavation,strictly avoiding undercutting.From the analysis of the construction effect,this method effectively controlled pit deformation and surface settlement,providing valuable guidance for similar future projects.
