核电站底板大体积混凝土防裂措施与总结

On anti-crack measures of large concrete of baseplate of nuclear power plants

从配合比、施工顺序、浇筑、养护及温控措施等方面,总结了恰希玛核电厂C3工程大体积混凝土的防裂措施,并结合大体积混凝土典型部位的温度变化情况,得出了温度的变化规律,针对部分无害裂缝的产生原因,提出了具体的防治建议。

From the proportional ratio, construction sequence, grouting, maintenance and temperature control measures, the paper sums up the anti-crack measures for C3 engineering large concrete, concludes the law for the temperature changes by combining with the temperature changes at the typical parts of the large concrete, and points out some suggestions for the reasons for the cracks.
