城市公路隧道二氧化氮浓度控制及通风方案研究

在含有二氧化氮（NO2）的环境中，过高的二氧化氮浓度对人体的危害很大，但在公路隧道设计规范中，却没有对二氧化氮浓度排放标准进行规定。为了保证城市公路隧道行驶机动车内人的健康、卫生和隧道的营运安全，以某隧道（620m）工程为例，结合隧道智能监控系统数据分析，提出在城市公路隧道内二氧化氮浓度的排放限值，以及相应的通风方案，为城市公路隧道监控系统软件设计提供参考。

Research on NO_2 Concentrations Control and Ventilation Plan for Urban Highway Tunnel

In the environment of containing nitrogen dioxide(NO2),too high nitrogen dioxide concentrations will be great harmful to human body,but in the design specifications for highway tunnels,nitrogen dioxide concentration isn't regulated about the emission standards.In order to ensure the people's health,sanitation within the vehicles driving in urban highway tunnels and operational safety of the tunnels,taking a tunnel engineering as the example,combining the data analysis of intelligent monitoring system,this p...
