摘要:

针对某多匝道城市公路隧道,利用SES通风模拟软件研究通风孔布置、通风孔个数等因素对隧道内污染物体积分数分布、通风孔排污效率等通风效果的影响。结果表明: 1)隧道采用顶部开孔自然通风方式,可以有效减少隧道内及出口处污染物体积分数; 2)在匝道分岔点上方集中布置通风孔能达到较好的通风效果,开孔个数较少可减少土建投资; 3)隧道段过长污染物体积分数不能满足标准时,应在隧道段后部增设开孔。

Abstract:

The influences of layout and amount of ventilation openings on ventilation effects of multipleramp highway tunnel in urban areas, such as concentration of pollutant and ventilation efficiency of openings, are analyzed by ventilation simulation software SES (subway environment simulation). The analytical results show that: 1) The concentration of pollutant in tunnel and at tunnel exit can be effectively reduced by setting ventilation openings on tunnel roof. 2) Good ventilation effect will be reached by setting centralized openings above fork of ramps, which will result in a reduction of construction cost. 3) Ventilation openings should be increased especially at back section of tunnel when the tunnel section between two forks is too to meet ventilation standards.

Key words: multipleramp highway tunnel, ventilation opening on tunnel roof, natural ventilation, layout of opening, SES (subway environment simulation)
