摘要
结合国家重点工程天生桥一级水电站施工试验，分析了面板堆石坝坝体堆石料采料爆破的块度控制。重点研究了料和料现场试验和施工过程，满足设计堆石料块度级配要求的爆破参数调整。根据施工现场的特点，提出了采用修正后的ＫＵＺ－ＲＡＭ模型作为预报合理块度相应的采料爆破参数的数模．通过编程计算，达到在现场实时控制堆石料级配的目的。
Based on expsrience from construction of the Tianshengqiao I hydropower station (key project in China), size control after rock blasting for rockfill material of concrete-face rockfill dam with is studied. In-situ test and construction procedure for IIIA material and IIIB material and blasting parameters which meet the requirements of gradation for design rockfillmaterial size are mainly studied. According to in site construction features, a revised KUZ-RAM model is used as parametricmodel for predicting appropriate size of rock blasted. By programming and calculating, real time control of rock fill gradationin site is realized.
