Abstract:
To explore the decision-making method of highway tunnel face selection, a decision indicator system of three-layer highway tunnel face layout type is built according to the Longquanshan Tunnel Project of Chengdu Tianfu International Airport. The face layout scheme of three types of highway tunnels and their decision-making standards were determined to employ the fuzzy comprehensive evaluation (FCE) method to solve the decision-making problem of tunnel face selection. When the 4-tube layout is adopted in the Longquanshan Tunnel, the membership value of the Longquanshan Tunnel face is calculated to be 0.608 2 and the 4-tube layout is recommended. The practice shows that the decision-making system of highway tunnel face layout type proposed is highly reasonable and reliable.
