【摘要】 在城市高架道路的设计中 ,特别在交通繁忙的路口建造立交桥 ,由于施工条件、施工工期、高架下地面交通的布置和桥梁总体美观等限制 ,连续钢箱梁方案往往成为首选方案。连续梁一般在曲线段上成为连续曲梁。目前在上海延安路高架、逸仙路高架中已建成多座连续曲线钢箱梁。本文根据连续曲线钢箱梁的特点 ,探讨设计中应注意的若干问题 ,使连续曲线钢箱梁设计安全、合理、经济更多还原

【Abstract】 In the design of the urban overhead roads,especially to build grade separation bridge at the road intersections with busy traffic,because the limit of construction conditions,construction period,the layout of the surface traffic under viaduct and bridge overall beautification etc.,the option of continuous steel box beam often becomes the first selected option.The continuous beam becomes generally continuous curve beam on the curve section.Now several continuous curve steel box beams have been built on Shanghai Yang’an Road Viaduct and Yixian Road Viaduct.The paper approaches to some problems to be paid in the design in accordance with the characteristics of the continuous curve steel box beam so that the continuous curve steel box beam can be designed to safe,reasonable and economic.更多还原
