摘　　要：由于桥梁反复受到道路行车的磨损、冲击,遭受日晒、雨雪、冻融等自然因素影响,桥梁构件的耐久性和结构类病害不断增多,给桥梁管养工作带来巨大压力。文章详细介绍了桥梁检查方法,阐述了梁体、支座、墩台等桥梁构件耐久病害,提出了维修建议。同时,针对梁体抗力不足、基础稳定性等结构类病害问题展开分析,论述了相应结构加固方法的适用条件、基本原理及附加影响,对今后的桥梁管养工作具有借鉴意义。Due to the repeated wear and impact of road traffic on bridges,as well as the impact of natural factors such as sunlight,rain,snow,and freeze-thaw and so on,the durability and structural diseases of bridge components continue to increase,bringing enormous pressure to bridge management and maintenance.The bridge inspection methods are introduced in detail,the durability diseases of bridge components such as beams,bearings,piers,and abutments are elaborated,and the maintenance suggestions are put forward.At the same time,the structural diseases such as insufficient beam resistance,foundation stability,and so on are analyzed,and the applicable conditions,basic principles,and additional influence of the corresponding structural reinforcement methods are discussed,so as to provide reference significance for future bridge management and maintenance.
