20m T异型组合梁桥加固设计与施工

Reinforcement design and construction for 20m T-shaped composite beam bridge

介绍了某T异型组合梁桥采用体外应力体系进行加固的设计要点,通过对加固前后的各截面进行计算比较,证明加固方案可行,并着重阐述了施工技术,为采用类似技术进行桥梁加固的设计和施工提供了宝贵经验。

This paper introduces the reinforcement design points of T-shaped composite beam bridge by applying exterior stress system, proves the feasibility of the reinforcement scheme through calculating and comparing various sections before and after reinforcement, and mainly ex- pounds the construction technology, which has provided valuable experience for the design and construction of bridge reinforcement by using similar technique.
