摘要
依据实际工程检测资料对堆石的压实性进行了较为详细的分析,得出了堆石本身的性质和施工工艺对其压实性的影响规律。对比研究了堆石平均粒径的计算方法,认为加权平均粒径d与d50显著相关,d50是中间值,而d是直接计算求得的,体现了不同粒径组的综合作用,更切合定义。
Quality examination is a very important process in rolled rockfill dam. The character of rock compaction influencing on dam's quality is studied comprehensively by practical data. It shows that both the character of rockfill and filling craft have influence on the character of rock compaction. The two kinds of calculation method to average grain diameter of rock are discussed and studied. The results show that weighted average grain diameter embodies the comprehensive actions by different fractions and keeps in line with definition more accurately.
