摘要
针对大型渡槽结构动力响应问题,考虑槽内水体与槽壁的相互作用,采用三维有限元及时程分析技术,建立了大型渡槽结构动力响应分析的力学模型,对不同过水量下结构的动应力及动位移进行了计算分析,得出不同支座形式对槽体结构动应力及动位移的影响,为同类工程设计提供理论依据和指导。
In this paper, aiming at the dynamic response problem of large aqueduct structure, the mechanical model of large aqueduct structure considering the interaction between water and wall in aqueduct was set up by the FEM and the timing analysis technique. Then the dynamic stress and the dynamic displacement under different flux were calculated. The influence of the dynamic stress and the dynamic displacement of the aqueduct structure under different support were obtained and the theoretical source and instruction for the similar engineering were provided.
