Abstract
In southern China, The moisture condensation is common in the urban underground facilities due to the humid and rainy climate. In order to reduce the maintenance costs the natural ventilation should be used in urban pedestrian underpass as far as possible. The planar layout of the underpass is very important for its ventilation effect so as to avoid condensation problem. Taking the Cuiliu street pedestrian underpass in city of Wuhan as a typical case, the field test was carried out in this paper on the Z-Shaped pedestrian underpass, and analyzed its ventilation effect by the computational fluid dynamic (CFD) numerical simulation. Results show that outcomes of the numerical simulation are close to the measured data, which verifies the reliability of simulation method. Thus Z-Shape is a good layout plan because of the better ventilation effect so that it can effectively prevent the moisture condensation for the urban pedestrian underpass even in moist environment.
