等截面曲线箱梁桥设计参数分析

曲线箱梁桥由于其结构特点，被广泛应用于高速公路和高架桥，但其设计计算非常繁杂，设计参数大都参考已建桥梁或通过大量试算来选取，工作量非常巨大。该文对曲线箱梁桥设计参数进行了分析，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, moreover, the design parameters need to be selected by refering to the existing bridges or by trial and error method, so the design work is very time consuming. In this paper the design parameters of curved box girder bridges are analysed, in order that engineers are able to control the selection of the design parameters while doing the design work. 
