Utilizing of utility tunnel in the field of urban infrastructure can solve the problem of urban underground pipe network effectively,which acquired increasingly high degree of attention in recent years. However,there is only a few of research on operation & maintenance management of utility tunnel at home and abroad. It has not formed a completed and matured technology system of operation & maintenance management so far. Therefore,on the basis of extensive literature research,the key technologies of intelligent operation & maintenance management of utility tunnel were reviewed in this paper. Application and research and development status quo of related technologies were introduced,including visualization operation & maintenance management,intelligent monitoring,management platform and so on. The direction of application and research of relevant technologies were analyzed. Based on the review of the key technologies,we discussed and analyzed the technology challenges faced by intelligent operation &maintenance management of utility tunnel,such as data and technical standards,unified management platform,security management and so on. It is pointed out that,if these challenges were solved,intelligent operation &maintenance management mode will have a great significance on the long-term,healthy and sustainable development of utility tunnel.
