旧桥预应力空心板梁破坏性试验研究

Research on Destructive Test for Prestressed Hollow Slab Beam of Old Bridge

通过旧桥拆除的预应力混凝土空心板梁进行极限承载能力的破坏性试验,深入了解和掌握主梁在不同状态下的安全储备和极限状态承载能力技术状况,一方面可为该类桥梁结构的营运和养护维修管理提供有价值的参考,另一方面可为同类桥梁结构承载能力评定方法的研究提供基础数据。

The safety stock of main beam under different status and technical condition of ultimate bearing capacity are further understood and mastered by the destructive test for the ultimate bearing capacity that is performed by removing prestressed concrete hollow slab beam of old bridge. On the one hand, it can provide valuable reference for the operation and maintenance management of this kind of bridge structure; on the other hand, it can provide basic data for the research on the evaluation method for bearing capacity of similar bridge structure.
