| 摘 要： | 阐述了对位于八度烈度地震区的某大型泵站枢纽因其抗震设防等级较高,急需开展安全分析以保障其正常运行进行的研究。构建了考虑地基-基础-填土-结构-荷载相互作用的三维有限元模型,基于模态分析并采用反应谱法研究了八度地震区完建蓄水工况与运行叠加工况下该类型整体结构的抗震动力性能,以此获得其位移、应力等动力参数指标,为泵站结构技施设计复核提供了参考依据。

| Abstract: | This paper studies the urgency of implementing safety analysis on one large pump station located at earthquake zone with seismic intensity of viii.Three-dimensional finite element model considering interaction among subgrade,foundation,filling,structure and loading is established.Dynamic performance is analyzed based on the modal and response spectrum method under overlap conditions of water storage after construction and normal operation,then such dynamic parameters as displacement and stress are obtained.This paper provides references for design review and verification of overall structures of the pump station. |
