摘要
本文主要探讨了二滩大坝混凝土试件尺寸和骨料粒径对强度的影响,并应用多元回归分析,定量地揭示了试件尺寸、骨料粒径、龄期和灰水比等诸因素对强度的影响。
The paper mainly explores the effect of specimen size and aggregate diameter on concrete strength and guantitatively reveals the effect of the factors,such as specimen size, aggregate diameter, age and cement water ratio,etc, on strength by applying multivariate regression analysis.
