摘要
进行了水下桩基础桥墩的振动台试验研究。从试件模型、试验装置和工况设置等方面介绍了水下桥墩振动台试验的实施过程。通过模型试验,分析与讨论了动水力对桩基础桥墩地震动响应的影响程度以及不同地震动输入条件下结构与水的相互作用规律。试验结果表明水的存在会改变结构动力特性和地震动响应。
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.
