摘要
以某梁式柔性墩渡槽工程为背景，建立了水体－渡槽的主、次系统动力分析模型，分别采用时程分析法和振型分解反应谱法，对横向地震激励下该系统的地震反应进行了分析。研究结果表明，槽体中水体存在明显的晃荡作用，起到了ＴＬＤ的效应；当渡槽采用橡胶支座后，ＴＬＤ效应虽有所下降，但却构成一个ＴＭＤ与ＴＬＤ共存的系统。
With a beam type of aqueduct engineering with the flexible piers as the background, the dynamic analysis models for the primary and secondary systems of water aqueduct system are established in this paper. The time history analysis method and the response spectrum method are used to analyse the seismic response of the system excited by the horizontal transverse direction earthquake. The research results indicate that there exists obvious sloshing action in water body remaining in the aqueduct, playing a TLD role. When rubber bearings are adopted to support the acqueduct, despite the decrease in TLD role, the co existence system of TMD and TLD is formed. Accordingly, seismic reduction effect becomes so apparent that it is of important reference value for the aqueduct engineering design.
