Abstract
In order to study the influence of the layout of station buildings on the wind field characteristic, wind tunnel tests of wind load on the main roof and platform canopy of the **an West Railway Station are presented in this paper. Four 1:250-scale rigid models of the station with different characteristics were made. Not only the wind loading of the first phase station, but also the interference effect of the extension of the second phase station, the longitudinal gap of the platform canopy and the blocking rate of the interchange corridor on wind loading of the station were studied. The results show that the station roof, especially the overhanging eave mainly subjected to wind suction. Although the longitudinal gap of the platform canopy increases the turbulence intensity, the wind pressure on the upper and lower surface of the platform canopy tend to weaken each other. The extension of the second phase station will change the wind load characteristic of the first phase station roof and platform canopy obviously. Under specific wind angle, wind loading on large area of the platform canopy will change from wind suction to wind pressure. With the increase of blocking rate of the interchange corridor, both the wind pressure and wind suction of the platform canopy will be intensified.
