With the development of construction in cities and the exploitation of underground space, increasing excavation projects are conducted right above subway stations. Such excavation leads to ground settlement, deep-level strata heave near the excavation area, and the consequent uplift of the subway tunnels. To decrease the influence of foundation pit excavation on the metro tunnel in the foundation pit project, a numerical model was established based on the foundation pit engineering of the traffic hinge of the Tianjin West Railway Station project. The concordance between the simulation analysis values and monitoring practice results validated the feasibility of the numerical analytical method. This research will provide a guideline for application in the metro development of Tianjin. The method and research ideas are reasonable, scientific, and could provide beneficial references to similar projects.
