摘要：

In　order　to　study　the　effect　of　the　slope　and　longitudinal　velocity　on　the　maximum　temperature　under　the　ceiling,　numerical　and　experimental　studies　on　the　maximum　smoke　temperature　under　the　ceiling　in　urban　underground　traffic　tunnels　with　the　gradient　of　0~±5%　were　studied　in　this　paper.　The　results　show　that　the　maximum　temperature　under　the　tunnel　ceiling　predicted　by　Kurioka　model　agree　well　with　the　numerical　and　experimental　results　when　the　tunnel　gradient　is　0.　At　the　same　time,　the　revised　Kurioka　model　is　also　suggested　for　the　sloping　tunnels　by　the　authors.
