The Study On Key Technology Of Operation Safety Of Expressway Tunnel In East Sichuan

With the rapid development of traffic construction in the eastern part of Sichuan,the expressway provides a great convenience for material transportation and personnel exchanges in the east of Sichuan province.However,the unique geographical location and geological conditions of the eastern Sichuan region,highway tunnels.How to ensure the safety of the tunnel operation is also increasingly prominent.The operation safety critical technology research of highway tunnel can effectively prevent and reduce the occurrence of malignant security incidents.Through the safety demonstration of highway tunnel operation,the dangerous factors that lead to the accident of highway tunnel before the safety accident can be eliminated.It can reduce the black spot of the accident,and then protect people’s life and property safety.In order to further enhance the level of safety during the operation of Expressway Tunnel in East Sichuan area,more accurately grasp the security situation of highway tunnel operation in East Sichuan area,scientific,objective and reasonable,it is necessary to analyze the operation phase of highway tunnel in East Sichuan possible traffic safety of uncertain factors during the tunnel operation,reduce traffic accidents.According to the situation in eastern Sichuan region of Shaanxi highway during the operation,with potential safety problems from the tunnel traffic operation of Shaanxi Expressway project analysis,through the ventilation energy saving for safety critical measures of Shaanxi highway tunnel and tunnel control related research and analysis,in view of the shortcomings and the existence of security risks the exact control measures and improve the program,and then improve the East Sichuan highway tunnel operation safety level.
