本文通过空气动力学及污染物运动分析发展程序模拟台湾雪山隧道内的污染物浓度分布。车行上坡隧道塞车是雪山隧道的最大通风需求工况,雪山隧道通风设计最大的特点是将通风竖井和空气互换管道整合一体,故隧道塞车时的最大通风需求可由相邻隧道共同分担。通风竖井或空气互换处是隧道内空气最污浊的地方,通风设备运作使通风竖井或空气互换处的污染物浓度恰能符合安全标准即可;通风竖井较空气互换耗电但排污最有效,空气互换对平衡两隧道通风需求差都有优良效果,两者功能类似。本文模拟雪山隧道在数种不同交通流状况下的通风需求及隧道内的污染物分布。
This paper simulates the concentration distribution of pollutants in the snow tunnel in Taiwan through the aerodynamic and pollutant analysis program. Traffic congestion Up-hill tunnel traffic congestion is the maximum demand for snow tunnel conditions, the most prominent feature of the design of the snow-capped tunnel ventilation ventilation shaft and the air exchange pipe integration, so the maximum traffic congestion in the tunnel when the demand can be shared by adjacent tunnels. Ventilation shaft or air exchange at the tunnel is the most polluted air place, the ventilation equipment operation so that the ventilation shaft or air exchange at the concentration of pollutants just meet the safety standards can be; ventilation shaft air exchange than the power drain but the most Effective, air exchange to balance the poor ventilation needs of both tunnels have excellent results, both similar functions. This paper simulates the ventilation requirements of snow tunnel under several different traffic conditions and the distribution of pollutants inside the tunnel.
