摘要/Abstract

摘要： 我国南方湿热多雨的气候条件使得城市地下设施易出现严重的结露现象，为减小维护费用，城市地下人行通道需尽可能地采取自然通风方式，通道的平面布置形式对其通风效果、避免结露问题十分重要。以武汉翠柳街地下人行通道为研究对象，对Z型城市地下人行通道进行现场试验测试，并辅以数值模拟，检验分析了通道的通风效果。结果表明，数值模拟结果与实测数据接近， Z型地下通道是通风换气较优的一种布置型式，自然通风效果较好，不易结露。

Abstract: The urban underground facilities in the humid and rainy climatic conditions in southern China often results in the serious condensation hazards. In order to reduce the maintenance costs after the completion of these underground structures, the natural ventilation should be encouraged in the urban pedestrian underpass as much as possible. The layout of the underpass has a strong influence on its ventilation effect and the minimization of the condensation hazards. This paper presents the underpass project of Cuiliu Street in Wuhan. The insitu ventilation tests were conducted and the numerical analyses were performed to verify the effect of the natural ventilation. The results indicate that the numerical analysis results are close to the measured results from the insitu tests. The insitu tests and the numerical analysis results verified that the natural ventilation is a better way of minimize the condensation hazard.
