摘要
随着中国桥梁建设的迅猛发展,早年间施工完成的桥梁出现了不同程度的病害,尤其是位于曲线上的桥梁,在车辆离心力的作用下,梁体会出现不同程度的横向偏移,增加落梁的风险。基于此,文章根据某工程实例,从挂梁和支座的角度就梁体偏移病害进行分析,提出纠偏加固措施,为相似桥梁加固提供参考。
With the rapid development of bridge construction in China, the bridges completed in early years have suffered from different degrees of diseases, especially the bridges located on the curve. Under the action of vehicle centrifugal force, the beams experience different degrees of lateral displacement, which increases the risk of falling beams. Based on this, according to an engineering example, this paper analyzes the beam offset disease from the perspective of hanging beams and supports, and puts forward rectification and reinforcement measures, which provides references for the reinforcement of similar bridges.
