城市隧道内污染物控制标准和通风设计研究

Research on Control Standards and Ventilation Design of Pollutants in Urban Tunnels

城市隧道由于在地理位置、服务功能、交通特性、空气环保等方面与公路隧道不尽相同,隧道内污染物浓度控制指标与公路隧道也有区别,而目前我国还没有针对城市隧道污染物浓度控制标准的相关规范。基于此,依据隧道内污染物浓度控制标准的确定原则并参考国内外最新成果,提出城市隧道污染物控制种类及浓度标准,为通风系统的合理设置提供理论基础,保证隧道运营的环保性和经济性。

Urban tunnels are different from highway tunnels due to geographical locations,service functions,traffic characteristics and air environmental protection,etc.,and control indices for density of pollutants in tunnels are also different from highway tunnels,while as of now our country has not had the related codes to control standards for density of pollutants in urban tunnels yet.For this reason,this paper in accordance with determined principles for control standards for density of pollutants in tunnels and by reference to up to date achievements at home and abroad proposes control categories and density standards of pollutants in urban tunnels to provide theoretical basis for reasonable setup of ventilation system and guarantee environmental protection and economy of tunnel operation.
