Analysis of Fire Source Development Characteristics and Perception Parameters in Highway Tunnel

With the increase of the construction length of a single tunnel and the traffic density in the tunnel year by year, the consequences of tunnel fire are becoming more and more serious, and the tunnel fire has gradually become a catastrophic problem in the operation and management of highway tunnel. The cause of the fire in the highway tunnel is complex, but its root is due to the people, car, road and environmental individual elements or each element fault or uncoordinated between produce fire, fire in the occurrence, development process, show different material and energy characteristics, and present different change rule, which can analyze the parameters of the characteristics of fire formation process. However, due to the complex environmental factors in the tunnel, some perceived parameters of fire characteristics will be hidden. In order to get the effective characterization characteristics and robustness parameters in the tunnel operation environment, this paper studies the effective characteristics of the sensing parameters in the process.
