摘要： 中梁山隧道是在20世纪80年代中后期开始设计修建的我国第1条特长公路隧道,已开通营运15a。研究 了该隧道原有通风系统运行状况。对洞内CO浓度、烟雾能见度和风速等现场测试数据的分析表明,右线隧道现有 通风模式能满足现在交通的需求;左线隧道在现有通风模式下,烟雾能见度大大超出现规范规定,营运环境极差, 已不能满足现在交通的需求,需进行改造。并提出了改善营运条件的技术建议。

Abstract: Zhongliangshan Tunnel,designed in the 1980s and the first extraordinarily long road tunnel in China, has been running for more than fifteen years. At present, the amount of traffic which passed the tunnel was two times of the designed one. Therefore whether the ventilation system became outdated with the aging of the tunnel needs investigating. Based on test of the amount of carbon monoxide, somke visibility and wind velocity, and analysis of the data, it was concluded that the right tunnel ventilation mode could meet the current demand for transport; while the left tunnel needed improving due to its unqualified smoke visibility and poorope ration environment. Technical suggestions for better operation of tunnels were made.

Key words: road tunnel;operation environment, smoke visibility, ventilation of tunnel
