| 摘 要： | 粗集料间隙率VCRDRC是矿料结构稳定性及能否形成骨架的一个重要指标，当集料规格一定时，其与各粒径集料的比例有关，本文基于灰熵法，通过调整各粒径集料的含量，找出对VCRDRC影响显著性的粒径。分析结果表明，9．5～13．2mm集料影响显著，4．75～9．5mm的集料影响次之，13．2—16mm的集料影响最小，可以为骨架级配的优化设计提供科学依据。

| Abstract: | VCRDRC is an important indicator to determine the structural stability of aggregates,when the Aggregate Specifications are certain,the VCRDRC is determined by the proportions of the different sizes.The influence of the proportions to the VCRDRC is studied thought the grey correlation entropy.The result show that the main factor influencing VCRDRC is the Aggregate of the 9.5~13.2 mm,and the second factor is the Aggregate of the 9.5~13.2 mm,and the last factor is the Aggregate of the 13.2~16 mm.Base on the an... |
