摘　　要：小西湖黄河大桥为部分斜拉桥,采用薄壁箱形截面梁,为了解箱梁的剪力滞效应,对其进行了剪力滞效应的有限元理论分析和模型试验研究,结果表明,试验结果与理论分析结果基本相符。Huanghe Bridge on Xiaoxihu Lake is partially cable-stayed bridge,which uses the thin-wall box sectional beam.In order to solve the shearing stagnant effect of the box beam,it is to carry out the finite element theoretical analysis and the model test study of the shearing stagnant effect.The result makes clearly that the test result basically tallies with the theoretical analysis result.

关 键 词：剪力滞 部分斜拉桥 模型试验 薄壁箱形梁
