摘要
运用灰色系统理论,对影响二灰碎石力学性能的主要因素间的主次关系进行了分析,得到了级配、粗集料、细集料及结合料含量等因素对二灰碎石抗压、劈裂、抗弯拉强度及其相关模量影响的排序,为研究该材料的优化设计提供了一种科学的评价方法。
This paper applied the gray system theory to study the influencing factors of the mechanics performances for the lime flying-ash broken stone mixture, and acquired the influencing-level order of the factors of gradation, coarse, fine aggregate and binders content to the lime fly-ash broken stone mixture's compressive strength, split strength, tension-bending strength and other modules. This method can provide a type of scientific evaluating way for the optimization design of the base course mixture.
