摘要
碾压堆石体作为堆石坝的主要筑坝材料 ,其工程性质对堆石坝的安全性有至关重要的影响 ,现场测试表明碾压堆石体的颗粒组成和级配对压实度有直接影响 ,在工程设计、施工中应严格控制各粒组的百分含量和含水率 。
As a main material for constructing roller compacted rockfill dam, the engineering properities of roller compacted rockfill have a vital effect on dam′s security. It is proved through field tests that the particle composition and graduation of roller compacted rockfill affectits compactness directly. So in order to obtain largest dry density, the particle groups′ percentage and water content should be strictly controlled in design and construction.
