绩溪抽水蓄能电站强风化岩生产垫层料研究

Study on Cushion Material Preparation Using Highly Weathered Coarse-grained Granite

安徽绩溪抽水蓄能电站下水库开挖料中有大量的强风化粗粒花岗岩,强风化粗粒花岗岩易破碎并呈砂砾状,通过开展粗粒花岗岩制备垫层料工艺试验研究及相关检测工作,论证利用强风化粗粒花岗岩制备大坝垫层料的可行性。如研究成功,将变废为宝,充分利用弃料,减少弃渣。

The excavated materials from the lower reservoir of Jixi pumped-storage power station have abundanthighly weathered coarse-grained granites, which are easily broken into gravels. In the paper, the feasibility ofpreparation of dam cushion material by using of highly weathered coarse-grained granite is demonstrated throughtechnological experiment and detection. If successful, this method can help us make full use of the discarded material and make waste profitable.
