摘　　要：以玉皇阁整体顶升工程为背景,通过有限元分析软件ANSYS建立静压桩模型,并考虑接触非线性、几何非线性以及材料非线性等多种因素,进行了特征值屈曲分析和非线性屈曲分析,得出了上部有垫块钢管静压桩的临界荷载,对类似工程有参考价值。Based on the process of the lifting-up conservation project for Kaifeng Yuhuang Pavilion,this paper established the finite element modal of the jacked pile with ANSYS,as well as considered contact nonlinearity,geometric nonlinearity,material nonlinearity and so on,then the critical load of the jacked pile with blocks on the top was got,after eigenvalue buckling analysis and non-liner buckling analysis.The method and conclusion of this paper could be the reference for similar projects.
