摘　　要：透水混凝土作为一种环保型材料,在水利工程和道路工程等方面得到越来越广泛的应用。影响其性能的主要因素有:水灰比、骨灰比和骨料粒径。采用正交试验方法[L9(34)],以28d抗压强度和透水系数为性能指标,分析研究了3个因素及其不同的水平对透水混凝土性能的影响,并通过回归分析和极差方差分析确定抗压强度和透水系数影响因素的显著性大小,得出了骨料粒径和骨灰比对透水混凝土性能的影响较为显著,水灰比影响较小的结论。As a kind of environment-friendly material, permeable concrete is being used more and more widely in water conservancy engineering and road engineering, etc. The main factors affecting its properties are water-cement ratio, ashes ratio and aggregate size. This paper adopts three factors different levels orthogonal experiment, takes the 28-day compressive strength and permeable co- efficient as the index, analyzes the factors of permeable concret6s properties by three factors and different levels, and determines the significance of the main factors by regression analysis and variance analysis, draws a conclusion that the influence of aggregate size and ashes ratio is significant, water-cement ratio has little influence.
