摘要
高混凝土面板堆石坝沉降监测是土石坝关键技术之一,紫坪铺工程分20段安装埋设了56套沉降仪,仪器完好率高,观测数据完整。监测分析表明:沉降规律性好,坝料分区对坝体沉降影响小,截止到2005年6月底,最大沉降量为88.1cm,最大沉降量与坝高比为0.56%,坝体施工质量优良。
Settlement monitoring for high concrete faced rockfill dam is a key technology.Zipingpu dam is divided into 20 blocks in which 56 sets of settlement meters are embedded with complete observation data.Monitoring analysis shows that settlement is regular,effect of dam zoning on settlement is small.By the end of June,2005,the maximum settlement is 88.1cm,ratio of the maximum settlement to dam height is 0.56%.Construction quality of dam is excellent.
