某循环水渠桥梁检测评定及加固设计研究

Study on Detecting Assessment and Strengthening Design of a Cycling Water Channel Bridge

当桥梁结构无法满足承载力、通行能力等要求时,需要对桥梁进行加固或技术改造。而旧桥加固技术改造不同于新建桥梁,它是一项技术性较强的工作,一方面要求尽可能不损害原结构,另一方面要求加固补强的部分与原结构成为整体,共同工作。文中以某发电厂循环水渠桥梁为例,基于详细检测评定的基础上,进行了加固设计,可为同类桥型加固设计提供参考。

When a bridge can not satisfy the bearing capacity or traffic capacity,it needs strengthening or transforming technically. The strengthening or technical transformation of an old bridge differs from that of a new one as it requires more technology in that it requires no damaging the original structure and the strengthene dpart coinciding with the original parts. This paper illustrates the strengthening design of a cycling water channel bridge on the basis of a comprehensive detecting assessment, which provides some reference for the similar cases.
