摘要：

The　relations　between　crowd　flow,　evacuation　space　on　road　and　post-earthquake　fire　were　researched　to　solve　the　problem　about　road＇s　evacuation　under　the　influence　of　post-earthquake　fire　in　urban　seismic　weak　area.　The　flow　model　of　road＇s　evacuation　with　the　post-earthquake　fire　influence　was　established　based　on　system　dynamics　theory.　The　building　height　and　wind　speed　were　selected　as　sensitive　factors　to　simulate　under　two　states　of　certain　assumptions.　The　results　show　that　the　different　values　of　building　height　and　wind　speed　will　affect　the　spread　speed　of　postearthquake　fire　differently.　Reasonable　parameters　were　selected　for　the　system　dynamics　model　under　certain　acceptable　levels.　Corresponding　counter-measures　were　put　forward　to　improve　the　evacuation　capability　and　some　references　about　specific　implementations　for　urban　planning　on　earthquake　resistance　and　hazardous　prevention　were　provided　according　to　the　simulation.
