摘要
本文根据双曲拱桥的结构特点,分析了双曲拱桥桥型的优缺点及运营状况。并参照相关桥梁检测评定规范,结合双曲拱桥受力特点及常规的加固工艺,通过实际工程案例分析了双曲拱桥提载加固的可行性。由桥梁加固前后静载数据对比分析表明,双曲拱桥提载加固能有效缓解目前的繁重交通量对双曲拱桥提出的巨大挑战,该加固工艺将产生深远的社会和经济效应。
According to the structure characteristics of the two-way curved arch bridge, the paper analyzes its advantages, disadvantages and the operating conditions. Referring to the relevant bridge checking evaluation standard, by combining with the mechanical characteristics and conventional reinforcement technology, the paper analyzes the feasibility of lift load reinforcement of a certain two-way curved arch bridge. The static load data contrast analysis of the before and after bridge reinforcement shows that the reinforcement can effectively relieve the heavy traffic and may have far-reaching social and economic effects.
