土石坝结构运行缺陷分类与分级研究

Research on classification and grading of structure defects of earth-rockfill dam in operation

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。

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.
