摘　　要：通过涌潮水槽试验对桥墩墩身涌潮作用力进行探索,分析涌潮压力分布及其变化特点,给出涌潮最大压力分布范围;研究强涌潮正向、斜向作用下分别位于迎潮面和隐蔽区的桥墩墩身受力差异,建立强涌潮对桥墩墩身作用力的计算经验公式。In the tidal bore flume,a model experiment was carried out about the tidal force acting on the pier body. This study analyzed the tidal pressure distribution and its variation characteristics,and obtained the maximum pressure distribution range of the tidal bore pressure. The force difference of the pier body in the upstream and concealed areas under the positive and oblique directions of strong tidal bore was studied. The empirical formula for calculating the force of the strong tidal bore on the pier body was established. The test results can be used as reference for the relevant bridge engineering design.
