Abstract	The finite difference method is used to analyze influence of depth excavation on the underground pipeline around the foundation pits of Fuming road station in Ningbo urban rail transit project construction. Soil reinforcement in passive zone is considered in this paper. Based on assumption of plane strain, calculation is carried out for 11 steps excavation in the most dangerous section. Influence of the excavation on horizontal displacement, stress of underground pipeline is discussed. Some valuable conclusions for construction practice are also drawn from the analysis. The results of this paper can provide a reference for the design, construction and protection of the underground pipeline in Ningbo city.
