浅析曲线半径对曲线梁桥设计的影响

Discussion on the effect of curve radius on curve girder bridge design

通过对多个曲线半径、相同跨径的钢筋混凝土曲线梁桥和相同跨径的直线梁桥进行结构计算,并对其分析比较,讨论了曲线梁桥内力及位移与曲线半径的关系,找到曲线半径对整个结构受力的影响规律,得出在平常设计中"以直代曲"的简化方法。

By structural calculating many curve radius, steel concrete curve girder bridge with same span and straight girder bridge with same span, and which were analyzed and compared, the relationship between curve girder bridge internal force, displacement and curve radius was discussed, and the influencing law of curve radius on whole structure force was got, and the simplified method of replacing curve by straight line was got in ordinary design.
