拱桥诞生于我国,适用范围非常广泛,其不但造型优美,具有民族特色,而且跨越能力很大。随着系杆拱桥跨越能力的提高以及传统吊杆在锚固体系、索体结构、防腐方案等方面的缺陷,使得中承式混凝土系杆拱桥会产生不同部位和形式的病害。不同的病害需采取不同的加固方法。本文归纳了混凝土系杆拱桥的常见病害和加固方法,并采用有限元方法对某工程实例进行了研究,针对不同的病害采取了不同的加固方法,得出了一些结论,可供同类工程的病害处理提供设计参考。
Arch Bridge was born in our country, the scope of application is very wide, not only its beautiful shape, with national characteristics, but also great ability to cross. With the improvement of the spanning ability of tied arch bridges and the defects of the traditional suspension rods in the anchoring system, cable body structure and anticorrosive scheme, the half-supported concrete tied arch bridges will produce different parts and forms of diseases. Different diseases need to adopt different reinforcement methods. This article summarizes the common diseases and strengthening methods of concrete tied arch bridges, and uses a finite element method to study a project example, different reinforcement methods for different diseases, and draws some conclusions for similar diseases Processing provides design reference.
