Abstract 当地下结构穿越液化土层，场地液化可能会对结构的动力响应产生影响。基于已开展的局部液化夹层场地地下结构离心机振动台模型试验，建立二维局部液化场地土–结构动力相互作用的有限元模型。计算模型考虑砂土液化后易产生剪切大变形的特点以及饱和两相介质与结构接触的非线性特性，通过与试验结果对比，验证数值模型的正确性，进一步分析土–结构接触非线性特性对结构地震响应的影响。研究结果表明：孔压的增长是由于地震作用的累积效应；近场砂土由于土结相互作用的存在超孔压比上升的更快，且由于土与结构变形不协调而更易消散；对于局部液化夹层场地，土结捆绑接触会放大结构的地震响应，随着地震动强度的增大，砂土层液化程度提高，场地非线性特性增强，土结刚度差异增大，土结界面采用捆绑接触所带来的误差越大，故应合理考虑土结界面接触非线性问题。
