With the rapid economic development of China, the State Council relocates Tianjin andhas made decision to construct it to be an international port city, economic center of northernand eco-city. More and more ideas, enterprises, talents and technology flocke to Tianjin andpromote the development of it. Growing demand lead to continuously outward expansion ofthe urban space, even so, the urban center pressure is still large, the urban traffic as the citylifeline is close to saturation, crowded roads of the city, noise pollution caused by blaring carsound, and greenhouse gases of vehicle emissions, all cause obstacles for the development ofthe city and is inconsistent with the advanced metropolis and harmonious eco-city. As theurban rail transit has the advantages of convenience, comfort, environmental protection,occupied less area and large transport capacity, etc. It shares urban public transport pressurewith road public transport system. At the same time, the extension of the rail expand theavailable urban area,and city scale also smooth ly expand. Therefore, urban rail transitconstruction project get the favour of all city managers, so a large number of urban railtransit project constructions are in full swing. But, due to huge investment, complexenvironment and long duration, urban rail transit construction projects faces a variety of risks.therefore, this paper through research and discussion of Tianjin urban rail transit project riskmanagement issues, hope to seek effective measures to avoid and reduce risk loss in theprocess of project implementation, to ensure the smooth implementation of urban rail transitprojects, and to achieve economic, social and environmental benefits.Taking the construction project of Tianjin Subway Line5as an example, this paperstudies the rail transit project risk management issues. Based on the review of relevantliterature and the analysis of theoretical methods,and learned from construction andoperation experience of rail transit at home and abroad, the paper focuses on the riskes facedby Tianjin Subway Line5construction project,such as economic risks,the operating andmaintenance risk, legal risk of default, resources and environment risk and so on, and makes qualitative and quantitative analysis of the risk factors, so as to proposes appropriate riskprevention measures.
