公路隧道通风斜井角度优化分析

Angle Optimization of Highway Tunnel Ventilation Shaft

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。

Partial structural change of major tunnel will affect the tunnel ventilation energy consumption significantly, particularly due to the construction conditions, when the inclination angle of shaft is set with small degree, which may result in large energy consumption for ventilation. If the energy consumption of ventilation is too large and causes high operation costs, it is necessary to build＇ a new ventilation shaft with small energy consumption. In this paper, energy consumption with different angles of shafts is concluded by studying the intersection of different shafts with the main tunnel.
