| Abstract: | The seismic problem of large-sized aqueduct in the South-North Water Diversion Project is discussed in this paper.Applying ordinary differential equation(ODE) solver and finite element method,its numerical model,dynamic characteristic analysis and vibration isolation analysis with LRB is briefly introduced.The analytical and semianalytical method based on ODE solver shows the accuracy and reliability in its results,therefore,it is particularly useful for the preliminary design of large-sized aqueduct.Finall... |
