桥墩的截面型式多种多样，墩柱的优劣直接与桥梁的静、动力特性密切相关。不同桥墩型式使得墩柱的刚度不尽相同，桥墩刚度对桥梁的抗震性能、全桥的整体性等有显著的影响。采用双柱式、矩形薄壁墩、空心圆形三种不同截面来模拟桥墩刚度差异，通过建立全桥有限元分析模型，研究了不同桥墩型式下桥梁的自振频率、振型、地震反应位移及内力的变化规律，为桥墩的选型提供参考。

There are various section types of piers, the advantages and disadvantages ot whose pier stubs are directly and closely related to the static and dynamic performances of bridges. Different pier types make different stiffness of pier stubs, which have obvious influences on seismic performance and integrity of the whole bridge. Three kinds of different sections of double - column, rectangular thin - wall pier and hollow roundness are adopted to simulate the differences in stiffness of piers. The natural vibration frequency, vibration mode, earthquake response displacement and change rules of internal forces of bridges of different pier types are researched through building the model of finite element analysis of the whole bridge, providing reference for the selection of pier types.
