| Abstract: | In this paper, aiming at the dynamic response problem of large aqueduct structure, the mechanical model of large aqueduct structure which considered the interaction between water and wall in aqueduct was set up by the FEM and the timing analysis technique in order to analyze the dynamic response of large aqueduct, then calculated the dynamic stress and the dynamic displacement under different flux. At last, the law of the dynamic stress and the dynamic displacement of the aqueduct structure under different flux was obtained and the theoretical source and instruction for the similar engineering is provided. |
