特长隧道局部结构变化,对特长隧道通风能耗造成很大的影响,特别是由于施工条件的限制,斜井的倾角往往设置较小,这样可能会造成通风能耗较大。如果通风能耗损失过大,运营成本高,就有新建一条能耗损失较小通风井的必要。通过研究不同倾角的斜井与主洞相交,得出不同斜井倾角的能耗。 The change of the local structure of the extra-long tunnel has a great impact on the ventilation energy consumption of the extra-long tunnel. Especially due to the restriction of the construction conditions, the inclined angle of the inclined shaft is often set to be small, which may result in large ventilation energy consumption. If the loss of ventilation energy consumption is too large, high operating costs, there is a need to create a new ventilation loss of energy loss. The energy consumption of different inclinations is obtained by studying the intersections of inclined shafts with different inclinations with the main hole.
