    IN-SITU EXPERIMENTS FOR DEEP CURTAIN GROUTING IN 150 M THICK OVERBURDEN DEPOSIT FOR SEEPAGE CONTROL IN HYDROPOWER DAM FOUNDATION AT XIABANDI,XINJIANG PROVINCE

      Abstract
    • The dam foundation of Xiabandi Hydro-junctionin Xinjiang,which is about 147.95m thick,is a typical deep-thick overburden deposit.Its mainly composed of glacio-fluvial deposit layers,alluvial-diluvial soil and gravel,soil lens.The structure is very complicated.In order to find a a appropriate construction technology of curtain grouting to prevent dam foundation seepage,a specific in-situ test process related to deep overburden of dam foundation was carried out.Through the experiment,the grout materal,mixture proportion,construction measures and parameter have been analyzed in detail.
