摘 要: 结合秦岭终南山特长公路隧道通风系统采用的竖井送排式方案,运用了CFD(计算流体动力学)方法对 该通风系统的竖井与隧道主体联络风道90°拐弯处进行分析,以确定出较佳的土建结构形式并计算出联络风道 90°拐弯处压力损失系数. Based on Qinling extra-long highway tunnel ventilation system, this paper mainly used CFD to analyze the rectangular curved turning comer of the connecting shaft with the purpose to determine the relatively better civil structural type and to compute the pressure loss coefficient in the rectangular curved turning comer.
