摘　　要：通过分析连续桥面简支梁桥柔性墩台的纵向受力及变形特性,提出新的计算模型——刚度耦合模型,用以进行柔性墩台纵向水平力的分配计算。给出算例,分别以刚度耦合模型和现有传统刚度模型进行计算,并对结果进行对比分析,得出刚度耦合模型更为安全的结论。This article through the analysis continual bridge floor simple support beam bridge flexible plat-form＇s longitudinal stress and the distortion characteristic, proposed the new computation model—rigidity coupling model, with carries on the flexible platform longitudinal horizontal force the distributed computing. Give the example, respectively carries on the computation by the rigidity coupling model and the existing traditional rigidity model, and carries on the contrastive analysis to the result, draws a rigidity coupling model safer conclusion.
