| 摘 要： | 通过仿真分析软件FZFX3D,以一个冬季开始混凝土浇筑的模型坝为例,计算了混凝土浇筑后表面一直裸露和浇筑后立即覆盖保温材料两种工况,分析了特定高程上混凝土的温度分布、热流量以及坝体整体温升,建议了冬季混凝土表面保护的最佳时刻。 |
| 关 键 词： | 早龄期混凝土 温度分布 热流量 散热强度 温升 混凝土保护 |

| Abstract: | Based on the simulative analysis software-FZFX3D,two different conditions: the concrete surface is to be covered with or without curing insulation material immediately after the placement are calculated by taken a model dam,of which the concrete construction begins during winter,as the actual case.The temperature distribution,heat flux and temperature rise of the whole dam body on a specific elevation are analyzed,and then an optimal time to begin the concrete surface protection for the curing during winter is proposed herein as well. |
| Keywords: | concrete at early age temperature distribution heat flux intensity of heat emission temperature rise concrete protection |
