| 摘要 | 本文透過空氣動力及污染物運動分析發展程式模擬臺灣坪林隧道內的污染物濃度分佈。車行上坡孔道塞車是坪林隧道的最大通風需求狀沿，坪林隧道通風設計最大的特點是將「同共通風豎井」與「空氣互換管道」結合為一體，故單孔道塞車時的最大通風需求可由另一孔道共同分擔。通風豎井或空氣互換處是隧道內空氣最污濁的地方，通風設備運作使通風豎井或空氣互換處的污染物濃度恰能符合安全標準即可；通風豎井較空氣互換耗電但排污最有效，空氣互換對平衡兩孔道通風需求差異有優良效果，兩者功能類似，本文模擬坪林隧道在數種不同交通流況下之通風需求及隧道內之污染物分佈。 This paper studies the aerodynamics and ventilation of Pinglin tunnel, which employs a longitudinal ventilation system and uses an air interchange system as an auxiliary. The two tubes of Pinglin tunnel have opposite peak traffic cycles. The largest fresh air demand of Pinglin tunnel occurs when the uphill tube has a peak traffic with a high percentage of heavy trucks. The individual ventilation of the two tubes can be combined as a whole by “common ventilation shafts” and “air interchange system”. The less polluted tube acts as an auxiliary ventilation shaft of the more heavily polluted tube. The pollution level is highest at the locations of shaft. The ventilation requirement in each division is to guaranty that the pollution level does not exceed the legal standard. Control process is greatly simplified by setting the quantity of inflow air equals to outflow air in common shafts and interchange ducts. It has been found in this study that a smaller ventilation flow in shafts plus a larger flow in interchange ducts is the most energy saving operation mode. |
