中文摘要：
摇桌子的地震模拟的模型测试是一个重要方法学习桥结构的地震设计。以便为开发更多的可靠设计过程评估地震反应和 pile-water-pier 系统的动态特征，包括堆积 groups-cap-pier 和惯性质量，一个沉没的桥墩系统的摇晃的桌子模型测试被进行。因为相应于不同测试目的不同类似法律影响了测试结果的有效性，有目的类似法律通过一个实际例子被建议考虑水动力学压力的效果并且证实。基于测试结果，在在地震刺激输入下面的地震反应上的模型附近的水的效果被分析，失败水平被观察基本频率的变化判定。测试结果显示没有水，有水的分析模型的转移功能与那不同，没有水的自然频率与水总是比那高，并且第一形式的形状是各种各样的。类似法律对实际申请和动态特征合适，因为包围的水的存在，结构系统的地震反应能被改变，这也被结束，它应该在进一步的调查被付许多注意。
英文摘要：
The model test of seismic simulation shaking table is an important method to study the seismic design of bridge structure. In order to evaluate the seismic response and dynamic characteristics of pile-water-pier system for developing more reliable design procedures, shaking table model tests of a submerged bridge pier system, including pile groups-cap-pier and inertia mass, were conducted. Since different similitude laws corresponding to different test objectives affected the validity of test results, the similitude law with the aim to consider the effect of hydrodynamic pressure was proposed and confirmed through an actual example. Based on the test results, the effect of water around model on seismic response under seismic excitation input was analyzed and the failure level was judged by observing the variation of basic frequency. The test results indicate that the transfer function of analytical model with water is different from that without water, the natural frequency without water is always higher than that with water, and the first modal shapes are various. It is also concluded that the similitude law is suitable for practical application and the dynamic characteristics and seismic response of the structure system can be changed because of the existence of the surrounding water, which should be paid much attention in the further investigation.
