宁波市机场路北外环立交工程桥梁设计

摘要

According to the introduction of the bridge project of north circumferential overpass project at Jichang Road of Ningbo,the study sums up the principles and ideas for the bridge general design for interlinked overpass projects,illustrates the features of the simple-support and then continuous structural system,and the bridge experimental conclusion,and proves the advantages of the simple-support and then continuous hollow slab structure in the overpass projects.%通过对机场路北外环立交工程桥梁工程的介绍,总结了互通式立交工程桥梁总体设计的原则和思路,阐述了先简支后连续结构体系的特点和成桥试验结论,验证了先简支后连续空心板梁结构在立交工程中的优势。
