Abstract

Abstract: Based on the design of Qinling separ ated ex tra-long highway tunnel, this article mainly used CFD to analyze the flow pattern in the tunnel's opening area with the purpose to determine the character of the flow pattern and also this article raised some methods to reduce the cross infection in the tunnel's opening area.

Key words: tunnel engineering;computational fluid dynamics, ventilation, numerical analysis

摘要： 结合秦岭终南山分离式特长公路隧道设计方案,运用了CFD(计算流体动力学)方法对上下行相邻隧道进出口区域的流态进行三维数值分析,以确定出相邻洞口流态特性并提出了降低洞口流态交叉污染的土建工程措施.
