预应力混凝土桥梁加宽形式的探讨

预应力混凝土桥梁由于其结构上使用性能的优点而成为我国高速公路上的主要桥型,在高速公路的扩建工程中,必须重视影响拓宽预应力混凝土桥梁结构性能的因素研究,从而在拓宽设计、施工中采取相应技术设施,保证工程质量。本文探讨了预应力混凝土桥梁拓宽技术,并就新旧预应力混凝土桥梁的沉降、变形和拓宽图式等问题,提出有关工程建议。

Prestressed concrete bridge broaden form discussion

he prestressed concrete bridge the operational performance merit becomes on our country highway as a result of its structure in the main bridge, in the highway extension project, must take to affect the development prestressed concrete bridge structure performance the factor research, thus in the development design, the construction adopts the relevant technology facility, the guarantee project quality. This article has discussed the prestressed concrete bridge development technology, and on new old prestressed concrete questions and so on bridge subsidence, distortion and development scheme, puts forward the related project proposal.
