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, as vertical ventilation technology matures, more and more large and medium-sized tunnels use shaft-fed vertical ventilation, which must first determine the number of shafts and their spacing. In this paper, the method of calculating the number of shafts in tunnels under the same gradient is proposed according to the requirements of wind speed in tunnel ventilation. The influence of tunnel surface slope on shaft spacing is analyzed, and the method of calculating the length of tunnel under different gradient and the shaft Distance calculation method, and gives examples of analysis, the results of the study can be applied to the design of long tunnels in the relevant research.
