In order to solve the contradiction between the architectural function, architectural art and fire safety of the underground traffic square, the fire risk characteristics of the underground traffic square are analyzed. Based on the concept of functional safety collaborative design, referring to relevant engineering cases and standards at home and abroad, the fire protection design strategy of separating vehicle and personnel intensive area, separating vehicle area and station area, and refer to international standards to determine the fire compartment area and strengthen fire protection measures is proposed. Aiming at the underground traffic square of Hangzhou Qinwang Channel Project, the proposed fire protection design strategy is used for design. By setting the waiting area separately, the evacuation personnel in the bus and taxi station area are reduced by more than 35%, and the personnel are mainly concentrated near the evacuation exit. The simulation calculation is carried out by FDS and Pathfinder. The calculation results show that after the application of fire protection design strategy, the available safe evacuation time of people in the bus and taxi station area is more than 2.8 times the necessary evacuation time, which can meet the requirements of safe evacuation.
