Abstract:The underground logistics system used for container transportation is of great significance to solve the contradiction between the port cities in terms of traffic and environment. As a large underground project, there are many uncertainties in the construction and operation of this system. Different from the underground infrastructures of metro and highway tunnel, this system has the characteristics of automation and unmanned operation. Therefore, there is a certain particularity in the consideration of disaster prevention and reduction. Aiming at the risk factors of fire, flood and vehicle accident faced in the operation of this system, the discussion is carried out and the corresponding countermeasures are put forward, which has certain reference significance for the future security operation of this system.
