摘要

为了得到比较精确的大型双槽渡槽结构的地震反应,根据渡槽结构复杂、影响动力因素较多等特点,采用8结点空间块体单元对渡槽槽身和槽墩进行有限元离散,分别用耦合自由度和多个弹簧单元分别模拟渡槽槽身横向拉杆、加劲肋和盆式橡胶支座,建立了大型双槽渡槽结构地震反应分析的有限元模型,计算了南水北调水利工程中的双洎河大型双槽渡槽的振动特性,并分别用反应谱法和时程分析法对该渡槽进行了地震反应分析,计算结果可为该渡槽的抗震设计提供参考。
To get the precise seismic response of the largescale aqueduct with double troughs to dynamic loading, brick elements with 8 nodes are used to mesh the troughs and pier, for the aqueduct is a complex structure and there are some influencing factors on its dynamic performance. Coupled freedoms and spring elements are used to simulate the crosslinking components and pot type rubber bearing respectively. The finite element model (FEM) is established. Using this FEM, the natural frequencies and mode of the Shuangji river aqueduct used in the Project of Transporting water from South China to North China are calculated. The seismic response of the aqueduct is obtained by using response spectrum method and time history analysis method. The results may be served as the basis of structure design of the aqueduct.
