【摘要】 大型渡槽是灌区生命线工程中的关键性建筑物,其在地震及风载作用下的安全性已是渡槽建设的"瓶劲",也是国内外研究的热点。渡槽结构的抗震、减震和抗风技术的核心是渡槽结构动力学的问题,而渡槽结构动力学系属流固耦合(FSI)系统的动力学范畴。在已有研究的基础上,首先对渡槽结构FSI系统模型的研究进行了总结和评述;然后简述了渡槽结构动力特性和响应的求解技术以及抗震、隔震、减震与抗风技术的研究概况;最后总结了渡槽结构动力学的研究进展,提出了该学科进一步研究的内容和方法。更多还原

【Abstract】 The large scaled aqueduct is the key construction in the lifeline engineering of irrigation area,whose safety issue has become the "bottleneck"in the construction of aqueduct,especially,in the circumstances of earthguake and wind,meanwhile,it is a hot spot of research at home and abroad.During the construction of large-scale aqueduct,most important technical questions in earthquake resistance,seismic isolation,shock absorption and wind resistane techniques are structural dynamical problem.However,the aqueduct structural dynamics belongs to the category of fluid-solid interaction(FSI) system actually.The objective of this paper is to summarize and comment the results achieved in recent years based on the existing research in the FSI system of aqueduct.Firstly aqueduct model of FSI system was summarized and reviewed;then the dynamical properties and responses solution techniques for shock resistance and absorption and wind resistance of the aqueduct were briefly described;finally,the research advances in the aqueduct structural dynamics were summarized and the further study contents and methods was put forward,which will give a reference to the progress of the aqueduct structural dynamics.更多还原
