| 摘 要： | 重庆石板坡长江大桥复线桥是主跨330 m的世界第一大跨径梁桥,大桥主跨跨中103m梁段采用了钢箱梁结构,这样有效地降低了主梁的弯矩和剪力,正是采取了这样的措施,才使得如此大跨径的桥梁在技术和造价上都切实可行。

| Abstract: | The double-line bridge of Shibanpo Changjiang River Bridge in Chongqing,with a main span 330 m,is the longest span bridge of its kind in the world.The 103 m long portion at midspan of the main span of the bridge is used with steel box girder structure,which in that way effectively reduces the bending moment and shear force of the overall main girder.With the design measures in question,the double line bridge having such long span becomes practical and feasible both in aspect of construction techmiques and construction cost. |
