Abstract：
Analysing the characteristics of urban traffic link tunnel (UTLT) and the fire protection design of tunnel, puts forward applying the method of performance-based fire protection design (PFPD) to the smoke control and extraction design of UTLT. With the method of PFPD, studies and optimizes the smoke control strategies of five typical fire scenes in CBD UTLT, which will be built in Beijing.
