Analysis on Mechanical Properties of Tunnel Lining on Fire
The paper analyzes the fire-resistant performance of big tunnel structure by setting up the analyzing model of tunnel-surrounding, choosing the characteristics of concrete, according to the lengthways and crosswise temperature distribution in specific scene of fire, analyzing the temperature and stress field of the tunnel structure, and knowing the basic rules and the damage of the lining and inner equipment of the tunnel by high temperature which is set on the Shanghai Yangtze tunnel. Tunnel lining is made up of reinforced concrete duct pieces. Concrete is a kind of non-homogeneous composite material, which would experience complex changing both physically and chemically by the high temperature, and the changing will surely lead to the descent of the carrying capability of the integral mechanical properties. The thesis studies the basic rules of the tunnel on fire and the damage of the tunnel lining structure and the inner equipments by the high temperature, which is set in the Yangtze River Tunnel in Shanghai, thus contributes to analyze the demand of the joint action of the disaster prevention, the ventilation system and other equipment and to reduce the fire loss.
