摘　　要：参照内河墩柱梁板式码头结构形式,结合实际工程,采用有限元分析软件,建立码头含靠船墩排架结构模型,进行模态分析,得到该模型的固有频率和相应的振型,根据码头结构的受力特性,分析其薄弱环节,发现靠船墩在有高频的车辆或岸吊载荷垂直激励时会产生较大位移,为进一步动力分析、结构状态评估以及探讨该结构合理形式提供依据。With reference to the structural style of inland river pier beam slab terminal, combining with practical engineering, and using the finite element analysis software, we establish the bent model with pier structure, conduct the modal analysis, and obtain the natural frequency and corresponding vibration model. According to the mechanical characteristics of the pier structures, we analyze its weaknesses and find out that under the high frequency incentive of vehicles or quay crane＇s vertical load, a greater displacement will occur. This provides a basis for further dynamic analysis, structure condition assessment and research of reasonable structure types.
