摘要
正交试验法试验次数少试验点代表性好,在样本数少的情况下能建立系统的二次正交回归模型,便于指导试验和生产。粒料稳定专用水泥的配合比设计是一种三组分最优设计,采用二因素二次正交回归实验方法对这种水泥的配合比进行了设计,得出了以7 d强度为考察指标的二次回归方程,并通过数值分析计算出专用水泥的最优配比,经过F检验,回归方程显著性好,最优配比准确,省去大量的实验工作量,正交回归是三组分设计的良好实验方法。
Less experiment workload is needed by using the orthogonal experimental design than using the trial and error method. The orthogonal experimental point has good representative, the quadratic orthogonal regressive system model can be set up to instruct the product and experiment without excessive test samples. The design of granular stabilizing cement proportion is a three ingredients optimization. The Quadratic Orthogonal Regressive Analysis is employed to design the granular stabilizing cement＇s proportion. The quadratic regressive equation is obtained on the investigation of 7 day compressive strength; the optimum formula of the special cement is obtained from this equation by mathematical analysis. The significance of the regressive equation is proved to be very good with the F inspection. The granular soil stabilizing cement optimum proportion obtained by this method is very accurate. A great deal of experiment workload is saved so that the quadratic orthogonal regressive analysis is very effective to be used as three ingredients material proportion optimization.
