Pressure measuring wind tunnel tests using rigid model have been carried out to investigate the interference effects of surrounding buildings on the wind load of the light rail station when the height ratios between the surrounding buildings and the light rail station are 0.66，1.08，1.50，respectively. The test results show that the horizontal wind load of the station is decreased due to the interference effect of the surrounding buildings. When the height of surrounding buildings is less than the station（height ratio=0.66，1.08），the vertical wind load of the station decreases. In the case of the height ratio =1.50，the vertical wind load increases when the wind angle ranges from 0° to 70°. The turbulent in the flow field is influenced by the surrounding buildings，which leads to the increase of the fluctuating wind load on the station. When the height of surrounding buildings is larger than the station，the vertical wind load increases obviously，and the interference coefficient is about 1.8. In addition，for the extreme wind load，the interference effect is also significant. When the height ratio =1.50，the extreme wind load on the roof and wall increases obviously. Specially，the extreme suction in the corner area of the roof increases by 12.5%，the increases of the extreme suction and pressure in the corner area of the wall reach 33.5% and 16.7%，respectively.
