Numerical simulation of static interference effects of three earth buildings

The static interference effects of three earth buildings and spatial distribution of wind pressure coefficient interference factor of interfered building surface were studied. The influence of different space and wind direction on static interference effect of building group was analyzed. The result showed that the wind interference is obvious, causing by earth building 2, when the direction angle is 0°. The wind interference are good when the direction angles are 45°. The change of building surface interference factor is not obvious with 1.0 D space,when the direction angle is 90°. Narrow effect is prone to develop and the interference factor is obvious, when the direction angle is 135°.
