对几种跨径布置形式的大跨径混凝土变截面连续箱梁在结构造价，施工风险，结构受力和施工精度等方面进行了论述，提出了在某些特殊地形下，采用边跨比小的连续梁桥可以比常规边跨比的连续梁更优的观点，为今后该类型桥梁的设计提供了一定指导。

This paper discussed large span concrete reduce section continuous box girder of several span layout forms in structural cost, construc- tion risk, structure stress, construction accuracy and other aspects. Put forward the view that in some special terrain, using continuous box girder with small side span was batter than continuous box girder with conventional side span. Provide certain guidance to this type of bridge design.
