摘要
江坪河混凝土面板堆石坝,是当前国内外的第二高坝,坝体材料采用栗山坡料场的冰渍砾岩(Zant)。目前,国内外尚未见采用冰渍砾岩填筑高面板堆石坝的工程实例,在可研阶段对筑坝材料进行了现场爆破和填筑碾压试验,但由于爆破料的级配尚未达到良好级配的要求,而压实密度(孔隙率),虽然采用目前国内吨位最大常规振动碾压,但密度(孔隙率)仍不理想,所以此次引进冲击碾进一步进行试验研究。
At present,Jiang Ping River CFRD is the second dam in domestic and foreign.Dam material use the ice stains conglomerate of chestnut hill yard.And there is not engineering example which use ice stains conglomerate to fill high concrete face rockfill dam.In the research phase,taking materials of dam to on-site bursting and filling rolling test.However,due to blasting not yet reached the gradation requirements of good grading and compaction density（porosity）.Although we use the maximum tonnage of domestic conventional vibrating rolling,the density（porosity） is not satisfactory.Therefore,we introduced the impact grind to pilot study of further study.
