摘要

以景洪水电站水力式升船机塔楼及上部机房结构振动台模型试验为例,通过有限元软件ADINA中势流体单元分析了水体和结构的相互作用问题,探讨了竖向地震激励对充水塔楼结构及上部机房的影响。结果表明,竖向地震动可致此类有限空间内动水压力有所增加而对系统动力响应影响轻微,可为类似结构的抗震设计提供参考依据。
Taking the vibration table model test of ship lift tower and upper room structure for Jinghong Hydropower Station for an example,the interaction of water body and structure is analyzed by using potential flow element in ADINA finite element method software.And then the effect of vertical earthquake excitation on water-filled tower structure and upper bent system is discussed.The result shows that vertical earthquake can significantly increase the dynamic water pressure of the limited space while it has little effect on the system dynamic response.Thus,it provides reference basis for anti-seismic design of the similar structure.
