摘　　要：荒沟抽水蓄能电站上水库主坝坝基土状全风化带厚度大、分布广,是坝基的主要地层,对其工程性质的研究是勘察工作中的重点内容。通过可研、招标阶段坑探、钻探及试验,确认该土层是花岗岩风化而形成,可以作为大坝次堆区基础。在面板堆石坝设计中对该层的利用,既减少了料场开采量及弃渣量,又节省了工程量和投资。The lully weathered soil zone lrom the upper reservoir basin in Huanggou Pumped - storage Power Station is the main dam foundation,which is in weathered large thickness and wide distribution, and the research on the engineering properties of it is the key content in the investigation work. It can be verilied with drilling pitting and testing that the soil layer is lormed by weathering granite and it can be used as the base of secondary zone in dam. The use of lully weathered soil zone in the design of concrete lace rocklill dam,can reducing the produced quantity and the amount of slag, and the amount of engineering and investment can be save.
