Abstract: Based on the research and statistical analysis of operational defects of earth-rockfill dams, classification criteria for main defects of earth-rockfill dams are proposed. According to current specifications, structural characteristics and engineering experience, combined with domestic and international experiences and methods for grading typical defects of earth-rockfill dams, grading standard for defects of earth-rockfill dams is established based on the level of hazard.

Key words: earth-rockfill dam, defect classification, defect grading

摘要: 基于国内土石坝运行缺陷调研及统计分析结果,提出土石坝结构主要缺陷及其分类标准。根据现行规范、工程结构特性和工程经验等,结合国内外土石坝典型缺陷分级经验和方法,按照危害程度,构建土石坝缺陷分级标准。
