Regarding the problem that the overloading caused by hoisting operation can affect the adjacent pile foundation，this paper analyzes the hoisting operation’s stability and pile foundation stress. The paper uses the empirical formula to calculate the hoisting stability and adopts the finite element method to analyze pile body stress. The results reveal that the stability coefficient of hoisting operation，pile body stress，and horizontal and vertical displacements of pile top all meet relevant requirements. The overloading exceeds the design value under the hoisting operation condition. Although the stress and displacement of the pile foundation meet the code requirements，the internal force and displacement increase significantly. Therefore，the impact of overloading on structural safety should be rechecked.
