YANG Gao-shang1,PENG Li-min1,ZHANG Jin-hua2,AN Yonglin1(1.School of Civil Engineering and Architecture,Central South University,Changsha 410075,China;2.Hunan Province Communication Planning Survey and Design Institute,Changsha 410008,China)  
The tunnel evacuation design should firstly ensure the people's life safety.Therefore the occupant evacuation model——TUNEV(tunnel evacuation) was developed.The model contains simple database of the people's behavior and parameters of tunnel fireproofing structure.By the simulation results the deficiency of fire design can be found to provide references for people's evacuation scheme.Moreover,the model can also work as an adjutant tool of fireproofing exercises.This article described some relevant concepts of the model in detail and an evacuation simulation of an object-Xuefeng tunnel was given out by using this model.Finally the model's validation and actual application was described briefly.
