摘　　要：由于既有桥梁工程在运营过程中难免存在各种需要重点解决的病害问题,因此对其承载能力进行验算,并根据验算结果进行针对性加固设计则至关重要。文章以某桥梁工程为例,对其当前的承载能力进行验算,在此基础上进一步探究了该桥梁的加固设计技术要点。从加固后的验算结果来看,本次验算和加固设计取得了较优效果,有望为今后类似工程提供参考借鉴。Since the existing bridge project inevitably has various disease problems that need to be solved in the operation process,it is very important to check its bearing capacity and carry out targeted reinforcement design according to the check results.This paper takes a bridge project as an example to check its current bearing capacity,and further explores the key points of the reinforcement design of the bridge.From the results of the check calculation after reinforcement,this check calculation and reinforcement design have achieved better results,which is expected to provide reference for similar projects in the future.
