【正文】 velopment of traffic infrastructure in our country, tunnel engineering has bee an important part of highway system. It has a significant impact on the optimization of road alignment, shorten the length of highways and to promote the environmental protection, and landscaping, local economic development and national defense construction also has a farreaching impact. Qing Qiaopu tunnel is located in Xixiang County of Shanxi City, Hanzhong province. It belongs to the ten day highway, Shanxi line, the eastern section of Hanzhong. It is the longest horizontal highway transportation corridor built in China. Tunnel line considering topographical and geological conditions, in the lining of the calculation, consider the elastic force presence, tunnel planning and designing process to follow and give full play to function of basic principles of the construction of tunnel, tunnel safety economy, plete the preliminary design of the tunnel. Qing Qiaopu tunnel startstop pile No. K44+050~K45+847, length 1797m, one side slope, slope is %. Tunnel lining use three circular curved wall lining. Portal with wing wall tunnel portal, materials for the M10 cement mortar calculation by 900 jet ventilation fan, a total of 17 units according to the single row layout. Lighting is divided into entrance section, transition section, the middle section, export and emergency parking strip the five part, rational design. Keywords: Tunnel, Structural calculation, Lining design, Waterproof and drainage, Ventilated, lighting。 I 目錄 摘要 .........................................................................................................
