为研究长大公路隧道巷道式施工通风的流场分布，利用流体力学研究软件Fluent建立隧道三维模型并进行了数值仿真计算。通过分别对隧道内部、主洞与横通道连接处流场特点的研究，分析了隧道内部流场分布的特点。模拟结果表明：巷道式施工通风隧道整体流场分布复杂，存在多个涡流区；横通道与主洞气流汇合向洞口方向流动约85 m后流速稳定。
為研究長大公路隧道巷道式施工通風的流場分佈，利用流體力學研究軟件Fluent建立隧道三維模型併進行瞭數值倣真計算。通過分彆對隧道內部、主洞與橫通道連接處流場特點的研究，分析瞭隧道內部流場分佈的特點。模擬結果錶明：巷道式施工通風隧道整體流場分佈複雜，存在多箇渦流區；橫通道與主洞氣流彙閤嚮洞口方嚮流動約85 m後流速穩定。

To study the flow field distribution of long High-way tunnel by roadway construction ventilation, three - dimen-sional models of the tunnel is built and simulated numerically with the software Fluent based on fluid dynamics theory. By stud-ying on the flow field features of the whole tunnel and main tun-nel connecting with cross -channel, analyzing the specific fea-tures of the flow field distribution. The simulation results show that the flow field distribution inside tunnel is complex,there are some eddy zones;the gases from main tunnel and cross-channel flowing direction of the hole about 85m is close to stable.
