In terms of the improper intensity distribution of foundation pile in the civil engineering, a 3D physical model of foundation piles was established. Based on the Simple algorithm, using RNG k-
turbulence equations and finite volume method, the control equation was discretized. With the wind speed of 10m/s, the flow field distribution of foundation pile was analyzed. The result shows that the middle part of the foundation pile is greatly affected by the wind power and is vulnerable to damage, and if the surrounding field undergoes stable-fierce?stable periods, parts of field will be vulnerable to damage. It is thus important to stress the consolidation, develop the flow resistance characteristics theory of the foundation pile and provide references for the actual project.
