运用灰色系统理论,从水泥稳定碎石材料组成角度出发,以水泥剂量和品种、集料级配、压碎值、含水量等值为参数,建立了7d龄期强度的灰色预测模型,适用性验证表明实际工程数据的预测值与实测值相比,其最大误差(95%概率)小于15%,预测效果令人满意,从而为该材料的优化设计提供了科学依据。
Based on the gray system theory and the composition of cement stabilized macadam materials, a gray predictive model of intensity at 7 days was established based on the parameters of cement dosage and variety, aggregate gradation, crush value and water content. The applicability The verification shows that the maximum error (95% probability) of the predicted value of the actual engineering data is less than 15% and the prediction result is satisfactory, which provides a scientific basis for the optimal design of the material.
