Freeway is an important part of modern transportation system,and has the characteristics of large traffic volume and high driving efficiency.However,with the expansion of freeway construction scope,the proportion of extra-long tunnels in highway projects has increased.Tunnel fire is a common risk during the operation of freeway tunnels and can cause serious damage.Therefore,this paper studies the specific application of fire alarm system technology in freeway extra-long tunnels,and clarifies the idea of realizing the design of fire alarm system in freeway extra-long tunnels,hoping to strengthen the safety monitoring of extra-long tunnels and ensure the safety of freeway operation.
