Tunnel safety risk identification method and device and safety management platform

The invention discloses a tunnel safety risk identification method and device and a safety management platform, and solves the problem that the safety of tunnel constructors cannot be powerfully guaranteed due to the fact that the risk of a tunnel construction operation area cannot be accurately and visually early warned in the prior art. The tunnel safety risk early warning method is used for tunnel safety risk early warning and comprises the following steps: for each process acquired in real time, acquiring the item number of the risk at each process position, and giving the process risk of each process and the evaluation value of each risk at the process position according to the item number of the risk at the process position; based on the process risk of each process and the evaluation value of each risk at the process position, performing superposition and summation according to the respective weight to obtain the construction risk evaluation value of each process; and according to the threshold range o
