摘　　要：就混凝土的胶凝材料、细集料、粗集料、水灰比对抗压强度的关系进行了参数回归分析。以多元线性回归分析方法对回归方案进行优化计算,选择优化方案,拟合了方程。运用方差分析及F值检验,观察方案的正确性和预测误差的大小,分析了拟合方程的可靠性。利用该拟合方程,初步分析出混凝土抗压强度参数关系。利用方程揭示的变量关系,可以从理化参数设计方面来指导商品混凝土的设计和生产,达到提高抗压强度的目的。The paper is engaged in parametric -regression analysis on concrete＇s cementitious material, fine aggregate, coarse aggregate and water - cement ratio against compressive strength. In this paper we optimize regression project with multivariate linear regression analysis and fit the equation. We observe correctness of the project and forecast the error by variance analysis and testing value F, and analyze reliability of the equation. We primarily analyze parameter relationship of compressive strength of concrete with the equation. This paper can direct design and production of concrete in the aspect of physical and chemical parameters design with variable relationship in the equation to improve compressive strength.
