| 摘 要： | 随着城市交通量不断地增长,为了缓解日益突出的交通问题,许多城市大量兴建隧道,而隧道废气集中排放又对隧道周边环境空气质量产生显著影响,长大隧道的排放影响更为明显.根据高斯模型和TOP模型理论,以某长大隧道为例,对城市长大隧道竖井排放和洞口扩散的环境影响做出分析.结果表明针对相同条件,CO的环境污染贡献率要比NO2的环境污染贡献率明显偏小;同时竖井高度并不能唯一决定污染物地面浓度大小,必须保证合理的排风量;此外,洞口废气扩散的环境影响要比竖井排放更为严重,并且洞口扩散作用受风向的影响也很大.

| Abstract: | With the continual traffic increase in the city,tunnels have been built in large amount in order to relieve the burden of traffic problem.But the centralized discharge of tunnel waste gas produces notable effect to the quality of tunnel ambient air,and the adverse effect of long tunnel discharge is more obvious.According to the Gauss model and TOP model theory,taking one tunnel as an example,the environmental effect of shaft discharge and cavern mouth diffusion is analyzed.Finally,the study results indicate... |
