特长隧道新建竖井引入自然风的通风节能分析

Analysis of Ventilation Energy Saving of Natural Wind Introduced by Newly Built Shaft of Extra-long Tunnel

以榆和高速公路云山特长隧道为依据,论述了特长公路隧道通过新建竖井引入自然风辅助机械通风的节能设计新方法,有效降低了隧道后期运营通风能耗,节省了维护资金,可为今后类似特长隧道的通风节能设计提供参考。

Based on the Yunshan Extra-long Tunnel in Yuhe Expressway,this paper expounded on a new method of energy saving of mechanical ventilation assisted by natural wind introduced by the newly built shaft of the extra-long tunnel,which can effectively reduce the ventilation energy in the later operation of the tunnel,and save maintenance funds.This paper can provide a reference for the ventilation energy-saving design for similar extra-long tunnels in the future.
