摘要
为了研究不同公路隧道形式相邻洞口的污染物窜流规律,以隧道通风速度和洞口间距为变量,对单向双洞、单洞连续以及双洞连续三种隧道形式的窜流洞口分别进行了数值模拟统计。根据模拟结果,从自由射流运动特征的角度,对比分析了三种洞口窜流的特点以及洞口外污染物分布情况及形成的原因。
In order to study the interporosity flow problem in different forms of highway tunnel, as the speed of tunnel ventilation and the tunnel spacing for variables, simulate the interporosity flow issue of the double-hole tunnel, the single-hole continuous tunnel and the double-hole continuous tunnel. According the results of simulation, in the perspective of free jet flow, analysis and illustrates the interporosity flow characteristic of the three types tunnel, also the reasons of the pollutant distribution.
