摘　　要：对于20世纪修建的现役桥梁及时进行相关的结构承载力评定,并提出科学合理的养护措施,进一步提高服役桥梁结构的寿命周期是极其重要的。结合已有桥梁力学理论和相关检测规范,通过桥梁缺损状况检查、桥梁材质状况与状态参数的检测、荷载试验等检测手段综合对现役桥梁的结构承载能力做出科学、客观、合理的评定。It is extremely important to timely evaluate the relevant structural bearing capacity of the active bridges built in the last century,and put forward scientific and reasonable maintenance measures to further improve the life cycle of the existing bridge structures.This article will combine the existing bridge mechanics theory and the relevant detection standards,and make scientific,objective and reasonable assessment of the structural carrying capacity of existing bridges by means of bridge defect inspection,bridge material condition and state parameter detection and load test.

关 键 词：桥梁缺损状况 材质状况与状态参数 承载能力检算
