摘要
根据虎山特长公路隧道的特点,对不同设计速度下隧道稀释CO的需风量和稀释烟尘的需风量进行了计算,综合比较各通风方案在通风设备费、施工条件、年度运营电费等方面的优劣,确定最优方案,对国内特长高速公路隧道的通风设计有一定的借鉴。
Based on the characteristics of Hushan Tunnel,an extra-long highway tunnel,the required airflow for diluting CO and the smoke at different designed speeds were calculated.This paper comprehensively compared the advantages and disadvantages of each ventilation scheme in terms of ventilation equipment fee,construction conditions,annual operating electricity fee,etc.,to determine the optimal scheme,which provide certain reference for ventilation design of extra-long highway tunnel in China.
