Tunnel flood early warning system and method based on fluid three-dimensional dynamic analog simulation

The invention discloses a tunnel flood early warning system based on fluid three-dimensional dynamic analog simulation, and the system comprises a data processing module which is used for storing a water inflow rate model; the model module is used for storing a slice model set for analogue simulation of the water level rise of the tunnel; the prediction module is used for acquiring future rainfall intensity, calculating the water inlet rate and calling the water level rising analogue simulation slice model; the display module is used for displaying the tunnel three-dimensional water level simulation video; and the emergency processing module is used for judging the risk level and outputting an emergency plan. The early warning method is high in early warning accuracy, long in time and timely. The tunnel flood early warning method comprises the following steps: establishing and storing a water inlet rate model and a slice model set for analogue simulation of tunnel water level rise; future rainfall intensity i
