高楼山特长公路隧道通风方案研究

针对高楼山隧道特殊的工程特点,本文展开通风方案研究。首先,借助规范及以往工程设计经验计算高楼山隧道的需风量,通过计算分析得出,全射流纵向通风不能满足高楼山隧道运营通风的需要,宜采用分段式通风。其次,通过对各分段式通风方案进行定量分析比选得出,高楼山隧道钻爆法施工采用2斜井送排式与射流风机组合通风方案,TBM导洞扩挖方案采用1斜+1竖井通风方案。

Research on ventilation program of Gao Lou Shan extra long highway tunnel

This paper unfolds the ventilation program research aiming at the special engineering characteristics of Gao Lou Shan tunnel. First of all, Required air volume of Gao Lou Shan tunnel is calculated based on the norms and previous engineering experience,through the calculation and analysis, the total jet vertical ventilation can''t meet the Gao Lou Shan tunnel ventilation needs, should adopt the sub-section ventilation. Secondly, in Gao Lou Shan tunnel,the drilling and blasting method adopts the scheme of the combination of the 2-inclined well and the jet fan,the TBM adopts 1 oblique Ventilation program through the quantitative analysis and comparison of the sub-section ventilation.
