Abstract: In order to systematically study theachievements and deficiencies in current work of fire safety standardization and research, basic concepts of urban utility tunnels were briefly introduced, followed by the development history of domestic and overseas utility tunnel systems. Then, related fire risks were analyzed, and differences between urban utility tunnels fires and common traffic tunnel fires were discussed. Thirdly, achievements and overall progress of urban utility tunnels fire safety research were reviewed from theperspectives of practical application and fundamental problems. Finally, differences between domestic and foreign fire codes as well as development of domestic standards were summarized, and a comprehensive outlook on future research directions was elaborated. The results show that research methods on fundamental problems were mainly those used in the field of traffic tunnels, and its research content is limited with topics being loosely connected. Moreover, its practical applications are mainly about discussions on engineering experience, and specialized fire codes are generally lacked.
