| description | Disclosed is a method for controlling wind pressure in a subway tunnel pressure relief hole, said method comprising the following steps: S1, a system collecting relevant parameters of a train, the parameters comprising train speed and train departure method; S2, the system gathering and adjusting working environment data, comprising tunnel area, air shaft area, hole opening area, and a route position setting; S3, the system establishing a pressure wave data analysis model and calculating tunnel section pressure change threshold distribution; S4, the system determining whether or not a simulation result meets a pressure comfort requirement, and if yes, ending a simulation, while if not, calculating the area, number and position of a pressure relief hole as well as a pressure relief air duct, and returning to step S2 and executing cyclically until a pressure requirement is met. Further disclosed is a system for controlling wind pressure in a subway tunnel pressure relief hole. The system may effectively mitigat |
