摘　　要：针对江阴至太仓高速公路峭岐枢纽多次跨越道路和河流且多为斜交的复杂状况,对其主线桥和匝道桥的结构设计和施工进行了介绍。结果表明,通过采用正交或反对称布孔、斜桥正做等技术措施简化了桥梁结构形式,通过采用独拉墩和错孔布置钢箱梁等施工措施有效地达到了与周围环境相协调目的。Oiaoqi interchange that on the Jiangyin to Taicang expressway spans roads and rivers with skewed bridge mostly.This paper introduces the structure design and construction of it＇ s main bridge and ramp bridges.It is proved that the bridge structure is simplified by arranging orthogonal or asymmetry spans and putting skewed bridge orthogonally, and the bridges are consitence with surroundings by taking single column pier and steel box girder with staggered arrangement.
