摘　　要：本文通过D_n—最优三分量二次倒数项混料回归试验设计,综合考察了流态混凝土的工作性、离析行为以及28天强度等特性与粗集料级配之间的关系。建立的数学模型反映了流态混凝土的主要工程性质与粗集料级配之间的内在规律。通过计算机优化求解,找到了相应约束条件下的最佳级配。对丰富流态混凝土理论、试验研究,乃至指导现场工程质量管理与控制十分有益。Based on the theory of Dn-optimum experimental design, this work studies the relationship between coarse aggregate grading and property of flowing concrete, including workability, segregation and 28-day strength. The symbolic models, pre-sented by three components second order Dn-optimum experimental design for mixtures regression with inverse terms, describes the law underneath between coarse aggregate grading and main engineering properties of.flowing ,concrete, the optimal grading of flowing concrete is found computer, and it is very useful to develop the theory of flowing concrete, experimental reseach and to guide the quality control of production.
