摘　　要：阐述了南水北调中大型渡槽的抗震问题,分别介绍了基于常微分方程求解器(ODE)和有限元方法的大型渡槽动力计算模型、动力特性分析和设置铅芯橡胶支座(LRB)的隔震分析。研究表明,基于ODE求解器的解析和半解析方法有很好的精度和可靠性,可用于大型渡槽的初步设计。结合所得的研究成果,对南水北调的渡槽抗震提出了合理化建议。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.Finally,some suggestions for seismic problem of large-sized aqueduct are offered for the South-North Water Diversion Project.
