| Abstract: | 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... |
