摘要 在港口抗震中采用循环弹塑性本构模型对港工建筑物的地震破坏机理进行数值分析与振动台实验。选取在港口建设中最常见的沉箱码头作为研究对象,采用循环弹塑性本构模型,FD-FE耦合方法模拟地震荷载作用下地基土液化导致的沉箱码头岸壁的整体失稳。然后通过水下大型振动台的模型实验进行验证。数值分析与模型试验破坏趋势基本吻合。结论表明:循环弹塑性本构模型在港口工程抗震理论研究中有一定的参考应用价值,为循环弹塑性本构模型在港口建设实际工程中的推广起到一定的铺垫作用。 The cyclic elasto-plastic model was used to analyze damage principle of port building through numerical analysis and shaking table experiments.Select caisson quay wall on the construction of ports as the object of study,use cyclic elasto-plastic model,FE-FD coupled numerical analysis method to simulate seismic response of large-size caisson quay wall under earthquake.Then adopt the under-water shaking table model experiments for verification.Comparing the results of different methods,destruction trend is similar.It is conclusion that cyclic elasto-plastic model is valuable in seismic theory and in the actual projects of ports plays a bedding role for promotion.
