| Abstract: | With the track traffic project of the Yang Village Mega Bridge of the Beijing-Tianjin Inter-municipal Railway as a practical example,a series of warm-keeping measures for construction in winter is introduced in the paper,with stress placed on the pre-heating of raw materials in the course of pouring concrete,ensuring the temperature of concrete when it is cast into forms,and the concrete-curing method by means of heat-retaining measures combined with warm-keeping measures after concrete is cast.All of those... |
