| Abstract: | The shaking table test for submerged bridge pier with pile foundation was performed.The test was introduced including models,equipment and work conditions.Based on the tests of pier models,the effects of hydrodynamic force on the pier with pile foundation were analysed and discussed.The interaction between structure and water was studied when various earthquake records were input.The results of test indicates that the water would change the dynamic characteristics and the responses of structures. |
