摘要:
在122.9 m高的足尺实验塔上，采用定流量法，对H管件每层连接的专用通气排水系统在排水立管顶部通气方式不同时（伸顶通气或侧墙通气）进行比对实验，探究顶部通气方式对排水系统内压力、通气流量的影响，从而研究其对专用通气排水系统排水能力的影响。结果表明：相比伸顶通气，采用侧墙通气会导致系统最小压力Psmin减小，进入专用通气立管顶部的通气流量Q2减小，排水能力下降。
Abstract:
On a full scale experimental tower with height of 122.9 m, special ventilation and drainage system with H pipe connected each floor with different ventilation modes (extended top ventilation or side wall ventilation) at the top of the drainage pipe was compared. The influence of the top ventilation modes on pressure and ventilation flow in the drainage system was explored, so as to study its effect on the drainage capacity of the special ventilation and drainage system. Compared with extended top ventilation, side wall ventilation led to a reduction of the minimum pressure (Psmin), ventilation flow (Q2) into the top of the special vertical vent and drainage capacity of the system.
