摘　　要：通过试验建立了水灰比与无砂大孔混凝土强度关系式,并根据试验数据统计计算出骨料品种对无砂大孔混凝土强度影响的回归系数αa和αb的取值为:碎石,αa=0.41,αb=0.04;卵石,αa=0.36,αb=0.19。研究结果可以作为今后无砂大孔生态护坡混凝土配合比设计的参考取值,对其他用途的无砂大孔混凝土配合比设计也有一定的指导意义。By establishing the equation between the water cement ratio and the strength ofmacroporous concrete without sand, and calculating the regression coefficients an,ab, of the test data, which reflect aggregate species how to influence the strength of macroporous concrete without sand. This was the result, crushed stone： an=0.41,ab=0.04; gravel： an=0.36, ab=0.19.If we wanted to design the mixture ratio of macroporous ecological revetment concrete,the research results could olav the role of reference value, and it also had certain guiding significances in other applications.
