混凝土刚架拱桥综合加固技术的研究与应用

Study and Application to the Comprehensive Strengthening Method of Concrete Rigid Frame Arch Bridge

混凝土刚架拱桥是一种非常实用的中等跨径桥梁结构形式。20世纪80～90年代,我国修建了相当数量的混凝土刚架拱桥,现在很多这种结构型式的桥梁存在病害。本文从混凝土刚架拱桥益发的典型病害着手,以某实桥加固为例,研究探讨了对这种桥型的综合加固技术措施。

Concrete rigid frame arch bridge is a kind of very useful medium span bridge.From 1980s to 1990s,many concrete rigid frame arch bridges were constructed,there is disfigurement among them.Taking example for an existent bridge,beginning with the typical damage of an example bridge,and studies and discusses the strengthening method of this kind of bridge is studyed anddiscussed.
