| 摘 要： | 在桥梁加固设计中，加固结构属于二次受力结构，在受力分析中必须考虑分阶段受力特点。根据这一受力特点，可建立桥梁加固正截面、斜截面承栽力的计算公式，同时采用塑性极限分析方法，有助于研究新老混凝土粘结面上的剪切强度。

| 关 键 词： | 桥梁加固 分阶段受力 正截面承载力 斜截面承载力 剪切强度 |

| Abstract: | In bridge consolidation design, the reinforcement structure belongs to twice loading structure, whose loading characteristic must be considered during its stress analysis. According to its stress characteristic, a formula for calculating the cross section and the diagonal section can be gotten, and the shearing strength is helpful to be studied using plastic limit analysis method. |

| Keywords: | bridge reinforcement stage loading bearing capacity of cross section bearing capacity of diagonal section shearing strength |
