摘　　要：以深圳市水官高速拓宽工程为依托,运用有限元软件ABAQUS对路基拓宽工程中的新老路基之间的差异沉降进行模拟分析,对拓宽路基在修筑阶段及工后运营阶段的变形特性、应力和孔压的变化进行研究,揭示拓宽路基差异沉降的规律和机理。Based on the widening engineering along Shenzhen Shuiguan Highway, the differential settlement between the new and existing subgrade there was simulated and analyzed with finite element software ABAQUS, as well as the deformation characteristics and the change of stress and pore pressure of the widened subgrade in the course of construction and the operation after construction were studied, which reveals the law and mechanism of widened subgrade＇s differential settlement.

关 键 词：拓宽路基 差异沉降 流固耦合 有限元分析 应力分析 沉降规律
