Claims (2)
- トンネル坑口近くに設置した走行車両識別装置の計測データに基づいて、立坑を連接した坑内排気口を備えた立坑集中排気換気方式道路トンネルへ進入する車両配列を、トンネル坑内を坑内排気口を境に区分けした複数の領域毎に認識し、この複数の領域それぞれ個別に、認識走行車両からの汚染物質発生量と交通換気風圧を演算することを特徴とする立坑集中排気換気方式道路トンネルの換気制御方法。
- 前記坑内排気口における排風機動作風量として、機械換気風圧補正係数および風圧効果の時間遅れ時定数に基づいて前記坑内排気口からの排出実効風量を求め、この排出実効風量から前記坑内排気口の風圧効果開口面積をトンネル断面積として機械換気風圧を演算して、前記複数の領域それぞれ個別に坑内風向風速を演算することを特徴とする請求項1に記載の立坑集中排気換気方式道路トンネルの換気制御方法。
