摘　　要：本文针对土石坝水库安全鉴定和除险加固工程勘察中出现的坝体填筑黏土料的压实度超过100%的现象,结合大量工程案例,从水库建设、运行、勘察检测手段和室内试验等多方面进行原因分析和评价,为处理土石坝水库在设计、建设以及安全鉴定和除险加固中遇到的填筑黏土料压实度问题提供参考。This paper analyzes the phenomenon of clay material compaction degree exceeding 100%in the construction of earth-rock fill dams for reservoirs,particularly in the context of safety assessments and risk mitigation projects.Drawing from numerous engineering cases,the analysis and evaluation encompass various aspects,including reservoir construction,operation,surveying and testing methods,and laboratory experiments.The aim is to provide insights and guidance for solving the issue of clay material compaction in the design,construction,safety assessments,and risk mitigation efforts related to earth-rock fill dam reservoirs.
