The foundation of wind turbine needs to have strong ability to resist incline deformation. In this paper, the reliability method is used to analyze the anti-inclination performance of gravity foundation of wind turbine. The circular gravity foundation placed in coral sands with no buried depth is taken as research object. The inclination angle formula of foundation under overturning moment is derived. On this basis the performance function of anti-inclination reliability of foundation is obtained. JC method is used to calculate anti-inclination reliability index. Influence of foundation dimension and overturning moment to reliability index is analyzed. Iterative calculation result shows that the method proposed in this paper can calculate anti-inclination reliability index quickly and conveniently.
