【Abstract】 Through the analysis of physical and mechanical parameters and chemical properties of materials,the influence of slurry concentration,sand cement ratio and curing age on the strength of filling body is discussed by using the method of three factors and four levels of orthogonal design.The results of variance analysis show that the order of importance of factors affecting the strength of filling body is:curing age > sand cement ratio > slurry concentration.更多还原
