公路桥梁结构加固设计方法探析

Analysis on the Design Method of Highway Bridge Structure Reinforcement

研究了公路桥梁结构加固的设计方法,在正确选择桥梁加固设计、加固方案原则的基础上,介绍了桥梁下部结构中,桩基、桥墩、承台的加固方法,桥梁结构表层的桥面铺装层、防水层以及混凝土表层的加固方法,桥梁上部结构中的增大截面加固法、体外预应力加固法、粘贴钢板加固法,并对不同的桥梁结构加固方法进行了对比。

This paper studies the design method of highway bridge structural reinforcement, and on the basis of the correct selection of the principles of bridge reinforcement design and reinforcement scheme, it introduces the strengthening methods of pile foundation, pier and cap in bridge substructure, bridge deck pavement layer, waterproof layer and concrete surface layer of bridge structure surface,strengthening method of increasing section, external prestressing and pasting steel plate in bridge superstructure, and compares different strengthening methods of bridge structure.
