Urban underpass tunnel waterlogging risk identification method and device and storage medium

The invention discloses a method and a device for identifying a waterlogging risk of an urban underpass tunnel, and a storage medium. The method comprises the following steps: acquiring basic data of the urban underpass tunnel; determining a catchment range; simulating the process that rainwater converges into the under-crossing tunnel through periodic calculation, and obtaining the amount of rainwater converging into the under-crossing tunnel at each calculation moment; calculating the water accumulation amount in combination with the pump station displacement; and on the basis of the first relation function of the accumulated water amount-submerged water depth of the underneath pass tunnel, the submerged water depth of the underneath pass tunnel is obtained, and then the waterlogging risk level of the underneath pass tunnel is judged. According to the technical scheme, the accumulated water forming process of the urban underpass tunnel can be reflected more truly, the accuracy of a waterlogging risk judgmen
