Abstract：

To　investigate　the　impact　of　different　slope　compositions　on　the　fire　environment　in　the　tunnel　with　herringbone　slope,　the　effects　of　different　tunnel　slope　combinations　and　fire　heat　release　rate　on　smoke　spread　and　temperature　distribution　under　natural　ventilation　were　analyzed　by　the　numerical　method.　Results　show　that　when　the　slope　of　the　small-slope　side　tunnel　is　1%,　the　natural　induced　airflow　speed　and　fire　environment　are　significantly　affected　by　the　slope　composition　on　both　sides　of　the　variable　slope　point,　and　the　induced　airflow　speed　is　proportional　to　(Q∗w　H′∗)0.　113　6.　When　the　slope　of　the　small　slope　side　tunnel　is　not　less　than　3%,　the　impact　of　the　slope　composition　on　both　sides　of　the　variable　slope　point　can　be　negligible.　Empirical　equation　for　the　maximum　temperature　rise　in　the　herringbone　tunnel　is　drawn,　the　maximum　temperature　rise　in　this　kind　of　tunnel　is　much　higher　than　that　in　the　horizontal　tunnel,　and　the　safety　of　the　tunnel　ceiling　above　and　close　to　the　fire　source　should　be　concerned.　©　2025　Beijing　University　of　Technology.　All　rights　reserved.
