Underground Traffic Space Engineering Fire Safety

Along with the rapid development of economy,expanding of scale of cities and the population,the traditional ground transportation has been unable to meet the demand for rapid development of city economic. many means of underground transportation turn up. More and more underground driveways are used. However,the fire accidents in underground driveways do serious harm to national economy and people's lives and property safety. How to prevent the spread of fire smoke, structural fire safety and safe evacuation of personnel and vehicles are important for underground space fire protection engineering.In this paper, a underground traffic space engineering in modern service industry was as research background, the numerical simulation of fire smoke flow control, evacuation and fire resistance for the main structure was carried out. the main works are as follows:(1) Through the analysis of numerical simulation results,the rule of smoke flow was attained,fire district was divide and programs doing better in smoke control were given in underground driveway.(2)Through the analysis of evacuation-related factors in underground driveway fire,the key parameters were obtained and evacuation and escape plan were given.(3) the main-structure model was established to analyze structural fire safety of the underground driveway,the temperature and distribution of internal forces were obtained and the structure of protection program were given.The results of fire smoke control,safe evacuation and structural fire safety can provide scientific basis for the underground driveway space fire protection design.
