Abstract: The traffic bridge and portal crane bridge at the dam crest of a hydropower station have been in operation for more than 30 years. In recent years, it is found that there are strong tremors when vehicles drive on it and the bridge beam slab has cracks and other defects. Therefore, it is necessary to carry out both visual and structural inspection of the bridge and evaluate its technical condition, so as to provide a basis for bridge maintenance as well as reference for similar hydropower stations.

Key words: concrete dam, bridge, structural inspection, technical evaluation

摘要: 某水电站坝顶交通桥、门机桥已经运行使用30多年,近几年发现过往车辆时震感较强烈,桥梁梁板有裂缝等缺陷,有必要对桥梁进行外观检查和结构检测,并对桥梁进行技术状况评定,为桥梁的维修保养提供依据,也可为类似水电站提供借鉴。
