高速公路桥梁下部结构加固改造分析

Analysis of Reinforcement and Reconstruction of Substructure of Expressway Bridge

为提高高速公路桥梁结构稳定性,以某高速公路桥梁下部结构作为研究对象,分析山区高速公路常见的几类桥梁下部结构病害,并结合工程实际,从桥台、桥墩、基础3个方面进行系统性分析,详细制订了高速公路桥梁下部结构加固改造设计方案。

In order to improve the structural stability of expressway bridges,this paper takes the substructure of a highway bridge as the research object,analyzes several types of bridge substructure diseases common in mountainous expressways,and combines the actual engineering to systematically analyze from the three aspects of bridge abutment,pier and foundation,and formulates the design plan for the reinforcement and transformation of the substructure of expressway bridges in detail.
