文章在分析二铰板桥梁病害类型与原因的基础上,通过与变结构为简支结构(桥下喷射混凝土)的方法对比,提出了使原结构转换为连续板结构的加固设计方案,并详细介绍了其设计与施工要点。通过实体工程验证得出该方案优点:加固方法简单,外观美观,技术要求低。 Based on the analysis of the types and causes of the two-hinged bridge disease, the paper proposes a reinforcement design scheme that converts the original structure into the continuous plate structure by comparing with the method of changing the structure to simply supported structure (shotcrete under the bridge) Introduced its design and construction points. Through the physical engineering verification obtained the program advantages: reinforcement method is simple, beautiful appearance, low technical requirements.
