| 摘 要： | 采用三维有限元方法对拱式U型渡槽结构进行了模态分析，包括空槽、3.5m水深（出于研究目的而采用的参数）、设计水深和满槽水深等工况。分析了流固耦合的渡槽结构的基本动力性能和水体对渡槽结构的影响，为渡槽结构的抗震设计提出了建议。

| Abstract: | The modal analysis of the arch_braced U _shaped aqueduct structure is carried on by using three_dimension finite elemen t method in the conditions of the aqueducts without water, with 3.5 m_depth wate r (adopted for the purpose of research), with designed_ depth water and with full_depth water. The basic dynamic characteristics of aque ducts considering fluid structure inter action, and the effects of liquid on the aqueduct structure are analysed, which puts forward suggestions for the seismic design of aqueduct structures. |
