摘　　要：概述了312国道常州改线工程新武宜运河大桥的设计工艺、特点和难点。因该桥主桥为三跨预应力混凝土连续箱梁,斜桥正做,错墩布置,边跨不对称设计,导致两边跨内力差异而造成配束困难。本文结合具体设计,介绍大边跨连续梁桥设计的成功经验以供参考。AIt introduced the charicteristies and problems of design of the crossing canal bridge.The main bridge fentured three stride prestressed concrete continous trunk girder structure.
