摘　　要：结合一座下承式钢管混凝土刚架系杆拱桥 ,介绍一种新型的预应力钢 -混凝土空心叠合板组合梁。有 2个主要特点 :采用现代体外预应力技术 ;采用叠合板组合梁新技术 ,实现双向组合。这种组合桥面体系在桥梁及建筑结构领域具有广阔的应用前景。Based on a through steel concrete rigid frame tie bar arch bridge, a new kind of prestresed steel concrete composite beam with overlapped open plates is introduced. It has two characters of adopting modern outside prestressed technology and a new technology of overlapped plates composite beam, and it can be widely used in bridge and structure engineering.
