摘要
阐述了桥梁加固的重要意义,重点研究了桥梁加固前后的桥梁性能参数的变化,对相对残余变位(应变)、跨中挠度和冲击系数各参数改善情况进行统计分析,总结了各参数的改善效果,为今后桥梁加固提供参考。
The significance of bridge reinforcement is elaborated,the changes of bridge performance parameters before and after bridge reinforcement are emphatically studied,the improvement of parameters like relative residual displacement(strain),midspan deflection and impact coefficient is statistically analyzed,and the improvement effect of each parameter is summarized,so as to provide reference for bridge reinforcement in the future.
