摘要
本文结合工程实例,对公路桥梁桥墩加固设计及加固维修技术进行阐述,针对该桥桥墩的现状及病害,分析了病害的产生原因,提出了三种不同的桥墩加固方案,并进行了对比分析。设计采用预应力砼护套加固,本文对其加固效果进行了分析,阐述了加固维修的施工工艺和流程,旨在为之后的工程实践提供一定的借鉴。
This paper describes the reinforcement design and reinforcement maintenance technology of highway bridge piers in combination with engineering cases. Based on the current situation and diseases of the bridge piers, the causes of the diseases are analyzed, and three different piers reinforcement plans are proposed and compared. The design is reinforced with prestressed concrete sheath, and its reinforcement effect is analyzed. Finally, the construction process and process of reinforcement and repair are expounded. It provides a reference for the projects in the future.
