摘要
以张唐铁路第一桥赤城白河特大铁路桥为依托,针对张家口地区高寒的气候特征,通过对比试验,重点分析了混凝土水胶比(W/B)、掺和料(粉煤灰)掺量、混凝土单位用水量(mW0)等一系列因素对桥梁工程混凝土抗氯离子渗透性的影响规律;通过研究发现:在混凝土抵抗Cl离子的渗透的影响因素中,水胶比(W/B)与单位用水量(mW0)产生的影响最为显著。
In this paper, Zhang Tang first railway bridge in Chicheng Baihe Long-span Railway Bridge as the basis, according to the climatic characteristics of Zhangjiakou alpine area, through the contrast test, analyzed the concrete water cement ratio（W/B）, Chan Heliao（fly ash） content, the unit water use of concrete（mW0） resistance to chloride ion permeability influence regularity of a system list of factors on the concrete bridge engineering; through the study found： in the factors of concrete to resist Cl ion penetration effect, water binder ratio（W/B） and water content（mW0） has the most significant impact.
