摘要
近年来,随着纵向通风技术的成熟,越来越多的长大隧道采用竖井送排式纵向通风方式,这种通风方式首先要确定竖井的数量及其间距。文章根据隧道内通风时对于断面风速的限制要求,提出了相同坡度下长大隧道竖井数量的计算方法,分析了隧道路面坡度对于竖井间距的影响,得到了不同坡度下隧道长度的折算方法及竖井间距计算方法,并给出了实例分析,其研究结果可以应用在长大隧道的相关设计研究中。
In recent years, longitudinal ventilation with shafts is increasingly used for ventilation of long tunnels in which the number of shafts and the spacing between them should be determined first. In this paper, the influence of road slope to the spacing between shafts is discussed and the method of calculating the number of shafts and their spacing is studied. An example is analyzed by using studies and design of long tunnel ventilation. this method. The research results could be used in the relevant
