刚架拱桥成本低,建造周期短,上世纪八、九十年代在我国进行了广泛的应用。不过刚架拱桥也有一个致命的缺陷——整体性较差,导致横向稳定性不够,有许多刚架拱桥已成为危桥。本世纪初,我国该类桥梁绝大部分进行了加固处理,但有些加固处理的方式选取不当,加固效果不佳,形成需要二次加固的局面。本文针对该类型加固后的桥梁状况,对刚架拱桥的常见病害及常用加固方法进行了分析评论,对以后的加固改造能提供一些借鉴。 Rigid frame arch bridge low cost, short construction period, the eighties and nineties of last century carried out in our country a wide range of applications. However, rigid frame arch bridge also has a fatal flaw - the overall poor, leading to insufficient lateral stability, there are many rigid frame arch bridge has become a dangerous bridge. At the beginning of this century, the vast majority of such bridges in our country were reinforced, but some of the reinforcement methods were not properly selected and the reinforcement effect was not good enough to form a situation requiring secondary reinforcement. In this paper, according to the condition of this type of bridge after reinforcement, the common defects of rigid frame arch bridge and common reinforcement methods are analyzed and commented, which can provide some references for the later reinforcement and reconstruction.
