摘要
凉风垭隧道系崇遵高速公路上单洞长度超过 4 0 0 0m的双洞单向行车特长隧道 ,本文结合工程实际情况 ,对主要的隧道通风方式进行了定性比选 ,优选了全射流通风方式和竖井送排分段纵向通风方式进行详细的经济技术比较 。
Liangfengya Tunnel is an extra long one-way tunnel with two tubes on Congzun Expressway, and the length of a tube is over 4000m. According to the practical engineering, the main ventilation modes of the tunnel are compared and selected in this paper. The detailed economic and technological comparison between the total jetting ventilation mode and the stepped vertical ventilation mode with blow and exhaust shafts is carried out. The operating ventilation mode for this tunnel is determined.
