          <datacite:description descriptionType="Abstract">トンネル火災時の煙挙動CFD解析と避難シミュレーションとの1-way couplingによって煙流動に影響された避難者の行動を求め，煙中で行動不能に陥っている要救助者の数によって火災安全性を定量的に評価する方法を提案した．煙による影響を簡略化して表すために，CFD解析から幅方向平均煙濃度分布を求め，さらに路面からの高さとその高さにおける煙濃度から判定する数段階程度の危険度を導入した．危険度をトンネル長さ軸と時間軸によるコンター図で表すことにより，火災時の煙の時間的な流動挙動を簡便な1枚の図で表すことが可能になった．避難シミュレーションはトンネル形状の特徴を考慮して一次元とし，トンネル利用者は避難の必要性を，天井部を流動する煙，他の避難者からの情報伝達，避難放送によって認識するとモデル化した．
\n The present paper proposed quantitative assessment method for road tunnel fire safety by numerical simulation of evacuation in smoke. To evaluate the influence of smoke on evacuees, Smoke Environment Level (&lt;i&gt;R&lt;/i&gt;) has been defined as a function of time and longitudinal location, by simplifying smoke distribution derived from 3-D CFD analysis and then weighting it with visibility. By mapping &lt;i&gt;R&lt;/i&gt; on time-distance plane, smoke's behavior in tunnel fire can be concisely expressed. In the developed 1-D evacuation simulation method using &lt;i&gt;R&lt;/i&gt;, each evacuee recognized the necessity of evacuation through smoke's behavior, other evacuees' behavior or emergency announcement. The number of people who were surrounded by thick smoke in 10 minutes was used as evaluation index for tunnel fire safety. The present method has been tested in the cases of various longitudinal gradients and evacuees' moving speed.</datacite:description>
