In order to ensure the safe operation of existing urban rail transit,the preliminary scheme research for the construction of new municipal infrastructure needs to focus on the protection of existing urban rail transit lines.Beijing Fengtai railway station,as an important transportation hub,has complex construction conditions for its surrounding municipal transportation facilities,especially the operation of Beijing metro line 10,which is a critical issue in municipal road design research.To ensure the smooth implementation of the municipal road connecting scheme,the feasibility of different schemes involving Beijing metro line 10 is analyzed from various forms such as viaducts,depot passages,and underground tunnels.Propose a three levels of fortification policy,namely the principle of"source control,process isolation,and end reinforcement",and flexibly adopt one or more forms as the directional strategy in the urban rail protection scheme based on the different influence of the railway affected area.Reasonable risk control scheme involving railways are proposed from multiple aspects such as design construction and etc.
