银川至百色国家高速公路重庆开县至城口(渝陕界)段满月隧道左右线分别长11446m和11428m,本文根据隧道埋深、需风量、通风井类型及数量、斜井施工运输方式提出了5种通风方案,对通风能耗、建安费、通风效果、防灾救援、工程地质问题、辅助主隧道施工等方面进行全面的技术经济比较,提出左线采用竖井送排分两段通风、右线采用一竖一斜分三段通风方案,并对推荐方案斜/竖井的最优排风比、经济风速和经济断面进行了分析,提出了满月隧道通风斜/竖井优化配置方案。论文的研究结论对满月隧道的通风设计提供了技术支撑,也对类似工程提供了参考。
According to the depth of the tunnel, the amount of air required, the type and number of ventilation shafts, and the construction and transportation mode of inclined shafts, the left and right lines of Manyue Tunnel from Yinchuan to Baise National Highway in Chongqing from Kaixian to Chengkou (Yu-shan sector) in Chongqing are 11446m and 11428m respectively. Ventilation scheme, a comprehensive technical and economic comparison of ventilation energy consumption, construction fee, ventilation effect, disaster prevention and rescue, engineering geological problems, auxiliary main tunnel construction and other aspects were proposed. Adopting the vertical and inclined three-stage ventilation scheme, the optimal ventilation ratio, economic wind speed and economic section of the proposed scheme are analyzed, and the optimal scheme of full-moon tunnel ventilation inclined / vertical shaft is proposed. The conclusion of the dissertation provides technical support for the ventilation design of the full moon tunnel and also provides a reference for similar projects.
