摘要
针对桥梁基桩在施工过程中可能产生的初始缺陷 ,指出常规有限元分析方法不能对此进行分析 ,而非线性有限元方法及失稳路径的弧长法可以较好地解决这个问题 ,通过ANSYS对桥梁基桩的屈曲计算分析得出存在初始缺陷时桥梁基桩屈曲的规律。
The traditional finite element analysis method can't analyze the initial defects that can be brought about during bridge base pile construction. But, non linear finite element analysis method and arc length method of losing stability path can solve this problem. By applying ANSYS analysis program to calculate the bucking of bridge base piles, some bucking rules when bridge base columns exist the initial defect are also given in this paper.
