  ABSTRACT: Early urban planning failed to fully consider the complexities of modern urban underground transportation. For example, underground tunnels passing through viaduct piles and the need for excavation of foundation pits beneath the viaduct piles for underground structure construction all significantly impact the stability of existing bridge systems. This paper studies the stability of viaduct piles after replacement due to deep foundation pit excavation. Based on the preliminary tunnel project of the Nanjing South Road Viaduct, a pile replacement scheme is designed, a three-dimensional numerical model of the viaduct’s stress system is established, and the impact of deep foundation pit excavation on the structure of the replaced viaduct and its surrounding environment is analyzed.
