Along with the constant advance of RCC damming technology in domestic, the applying scale expands incessantly, the technology of material achieves great progress too. 摘要随着我国碾压混凝土筑坝技术的不断进步，应用规模的不断扩大，筑坝材料技术也有了很大的进步。
The paper summarizes the study on material carried out by GHIDRI for years and induces the changing and developing trend of RCC mix proportion parameter selection for reference. 通过对贵阳勘测设计研究院多年来对有关工程进行的碾压混凝土筑坝材料研究，归纳了碾压混凝土配合比参数选择的变化及发展趋势，可为今后的有关工作提供参考。
