摘　　要：弯箱梁桥由于其结构特点,被广泛应用于高速公路和高架桥,但设计计算非常繁杂,工作量非常大.本文通过对两跨连续弯箱梁桥在偏心支承的影响下位移的分析,导出位移的经验公式,以供工程师在设计中参考.Because of its structural features, curved box girders are used as the structure for express ways and flyovers extensively, but its design caculation is too complicated. This text, through the displacement analysis of the curved boxgirder bridges, lead out the experience formula of the displacement, in order that engineers are able to control the selection of the design parameters.

关 键 词：弯箱梁桥 位移分析 偏心支承
