Abstract: The current situation and development trend of underground transportation facilities in Beijing are mainly presented in this paper. Then it analyzes the distribution, dynamics and future trends of groundwater in Beijing. The safety problems related to erosion, stability and structure material of underground transportation facilities, which are caused by the change of the groundwater level, are discussed. At the end of the paper, in order to solve the safety problems, some countermeasures and suggestions are provided.
