摘要
弯箱梁桥是近几年来高速公路和高架桥上使用较多的一种桥型.由于其结构特点,其设计计算非常繁杂,工作量非常大.本文通过对两跨连续弯箱梁桥在偏心支撑的影响下位移的分析,导出偏心支承与位移关系的经验公式,以供工程师在设计中参考.
Curved box-girder bridge is one type of bridges often used on expressways and flyovers extensively for recent years. Because of its structural features, but its design caculation it too complicated, moreover, the design work is very time consuming, This text, through the displacement analysis of the curved box-girder bridges with two spans under the influence of eccentric support, lead out the experience formula of the displacement, in order that engineers are able to control the selection of the design parameters while doing the design work.
