摘　　要：为了解某深水大跨连续刚构桥工作状况,对桥梁主体结构及附属构件进行外观检查与材质状况专项检查,结合水下摄像及探摸对主桥水下墩柱及承台进行检查,通过分析各构件病害标度与部件权重后综合评定全桥技术状况等级,为桥梁养护管理提出技术建议。In order to evaluate the working condition of a large continuous rigid-frame bridge in deep water, visual inspection and special inspection of material condition were implemented in main structure and ancillary components of bridge, and underwater videography as well as artificial fumble were applied in defects inspection of piers and pile caps in deep water. Finally, through analyzing the rating scales of members and weights of components, the related technical suggestions were given for bridge
