摘要
从通风设计的角度,总结了多匝道城市道路隧道的特征,在此基础上,明确了多匝道城市道路隧道设计参数取值方式,探讨了适用于多匝道城市道路隧道的通风方式,提出了三种通风方案,并针对水力相关型通风方案下的通风量计算,提出了“需风量逐次比例分配法”计算法。此外,研究了不同通风方案下风机动力与通风阻力匹配的问题,并提出了各匝道隧道与主线隧道之间的水力平衡方法。
From the perspective of ventilation design,the characteristics of road tunnels in multi-ramp cities are summarized. On this basis, the design parameters of such road tunnels are determined, the ventilation methods applicable to such road tunnels are discussed,and three ventilation schemes are proposed. In view of the ventilation volume calculation under the hydraulic related ventilation scheme, the calculation method of “progressive proportional distribution of air demand” is proposed;Additionally, the matching of fan power and ventilation resistance under different ventilation schemes is studied,and the hydraulic balance method between each ramp tunnel and the main tunnel is proposed.
