    A STUDY OF MATERIAL SEPARTING FROM GROUND WATER AT DAM FOUNDATION OF ANSHA HYDROPOWER STATION

    • It is kowen in first regular examination of dam safity in China that there exists material separating from ground water to different extent in drainage holes and draingage galleries at dam foundations or foundation corridors of many constructed and operating dams. Large amount and yaring composition of the material found in some dams have attracted sttension from experts and the relevant persongs of electropower stations. This paper provides a result of study of mineralogical and chemical conposition, physico chemical properties, and granulometric composition of surrounding water, rockmass on dam foundation and the material operatingfrom ground water by measurement and determination methods from engineering geological and hydrogical aspects,revearls the formation mechanism of the material separating from the ground water,and evaluates the effect of the material on dam safity.
