前言广州黄沙——芳村隧道为双孔四车道隧道,采用射流风机纵向式通风,这是一种诱导式通风系统,利用高速轴流风机从一端峒口诱导入大量新风,与隧道内汽车排出尾气不断混合后,污染空气从另一端峒口排出。隧道内空气污染浓度从入口到出口逐渐增大,在出口峒口处达到设计浓度值,污染空气从峒口排除扩散,对周围环境产生污染。当前大气环境保护问题已日益受到关注,无论是国外和国内隧道设计者都致力于环保研究,甚至对隧道外环境污
Preface Guangzhou Huangsha - Fangcun tunnel is a two-lane four-lane tunnel, using jet fan longitudinal ventilation, which is an induced ventilation system, the use of high-speed axial fan from one end of the mouth induced a large number of fresh air, and the car tunnel discharge After the exhaust gas is continuously mixed, the polluted air is discharged from the outlet at the other end. The concentration of air pollution in the tunnel gradually increases from the inlet to the outlet and reaches the designed concentration at the outlet of the tunnel. The polluted air is excluded from the outlet and is polluted to the surrounding environment. At present, the issue of atmospheric environment protection has received more and more attention. Both foreign and domestic tunnel designers are devoted to environmental protection research, even to the environmental pollution outside the tunnel
