大跨径预应力连续梁桥施工关键技术分析

Analysis of Key Techniques for Construction of Long Span Prestressed Continuous Beam Bridge

大跨径预应力连续梁桥,克服了混凝土结构跨度小、功能单一的缺陷,极大地发挥了混凝土材料的性能,提高桥梁的建设效率和质量。探讨大跨径预应力连续连翘的优缺点,并对大跨径连续梁桥施工中的常见问题进行总结,最后探讨了大跨径预应力连续梁桥施工的关键技术和施工控制要点,为大跨径预应力连续梁桥的施工提供资料参考。

The long span prestressed continuous beam bridge overcomes the defects of small span and single function of the concrete structure, which greatly improves the performance of the concrete material and improves the construction efficiency and quality of the bridge.This paper discusses the advantages and disadvantages of long span prestressed concrete continuous forsythia, and the large span continuous beam bridge construction in the common problems are summarized, and finally discusses the long span prestressed concrete continuous girder bridge construction technology and construction control points, to provide reference for the construction of large span prestressed concrete continuous girder bridge.
