随着桥梁使用年限的增长以及桥梁负荷的日趋增大,我国很多桥梁均出现了破损,因此研究如何修复这些桥梁已成为当今桥梁设计的重要课题。通过对目前我国大部分桥梁修复的实例分析,桥梁加固是维修病害桥梁、提高桥梁承载能力的最基本、最常用的方法,现提出了桥梁加固的目的,论述了桥梁加固的常见方法及特点,给出了桥梁加固的方案选择和加固效果评价。
With the increase of service life of bridges and the increasing load of bridges, many bridges in our country are damaged. Therefore, studying how to repair these bridges has become an important issue in bridge design. Based on the analysis of most existing bridges in our country, the bridge reinforcement is the most basic and the most common method for repairing bridges and increasing the bearing capacity of bridges. Nowadays, the purpose of bridge reinforcement is put forward, and the common methods and characteristics of bridge reinforcement are discussed. The scheme selection and reinforcement effect evaluation of bridge reinforcement are given.
