摘　　要：以江苏某高桩码头加固改造工程为例,分别建立平面和空间有限元模型,计算了不同荷载组合工况下改造后的码头内力情况。研究结果表明:(1)高桩码头加固改造工程按平面和空间两种计算方法在同一荷载组合情况下计算所得的桩基内力比较接近;(2)平面有限单元法将所有荷载简化后均作用在横向排架上,而空间有限元法则可根据荷载实际分布情况加载,两种计算方法对横梁内力计算结果差别较大。(3)根据平面和空间有限元计算方法的特点,对于比较重要和工程量较大的加固改造工程,建议用平面有限元法计算确定工程方案,用空间有限元法对主要构件进行内力分析与配筋。A project, which is a high-pile wharf being reconstructed and reinforced in Jiangsu, can be an exam-ple to be analyzed by plane and space finite element models separately and the internal forces of the reconstructed wharf were calculated under different loading combinations. The conclusions of the research show that：（1）Based on the results of plane and space calculation methods, the pile internal forces in the reconstructed and reinforced high-pile wharf approximate to each other under the same loading combination.（2）The plane finite element model makes all the loads assumed to act on the transverse bents after the simplification. However, the space finite ele-ment model can be loaded by the real loading distribution. Therefore, a great difference exists in the results of beam internal forces due to the two calculation methods.（3）According to the characteristics of the plane and space finite element calculation method, for the more important and large quantities of reinforcement and reconstruction project, the plane finite element method is suggested to use for the project plan, and it is suggested to use the space finite element method to analyze the internal force and arrange reinforcements of main components.
