大型拱式U型渡槽动力特性研究
Research on dynamic characteristics of the large-scal arch U-aqueduct
本文介绍了动力分析的反应谱法，并以某大型四跨拱式U型渡槽为例，基于常用的有限元软件ansys对其建立了三维空间有限元计算模型。对所建渡槽模型进行模态分析，依据模态分析结果和抗震动力设计要求对其进行反应谱法动力计算分析。由分析结果得出拱式U型渡槽动力响应的特性，对以后类似渡槽设计和动力计算有一定的借鉴意义。
his article describes the response spectrum method for the dynamic analysis, and taking a large four cross-arch U-aqueduct as example, established its three-dimensional finite element model based software ansys. Makes modal analysis for the aqueduct, and then does respectively seismic analysis with response spectrum method.According to the results of dynamic analysis,we get some Conclusions about dynamic response characteristics of the Arch U-Aqueduct that is a reference for design and dynamic calculation of the aqueduct in the future.
