摘　　要：冶勒水电站坝基为第四系堆积物，深度超过420m，其中第三岩组为弱胶结卵砾石与粉质壤土互层，设计在该地层帷幕灌浆深100m。通过两年多的现场灌浆试验，探索研究了浆材配比、灌浆工艺、灌浆机理、防渗效果检测等难题。本文拟对此进行简要回顾与总结。Dam foundation at the Yele hydropower station consists of accumulation in Quaternary system with depth over 420 m, in which the third rock group is interbed of weakly cobble and gravel and silty soil. Curtain grouting up to 100 m are carriedout in the formation. By in site grouting test over two years,grout mix,grouting techniques and mechanism,watertight effecttest are studied. The review and summery are presented.
