华龙一号核电站是中国自主研发的第三代核电技术,其安全壳混凝土的强度对结构自身强度和公众安全具有重大的意义,作为屏蔽结构重要部件之一的厂房基础不仅承担着支承结构的功能,而且是防止核泄露的重要环节,其对混凝土抗裂要求更高。华龙一号基础采用的多层段合并整体浇筑施工技术对缩短核电工期具有重要的意义,但大体积混凝土施工中的抗裂技术需要进一步研究。基于第三代核电站反应堆厂房大体积混凝土基础施工,通过开展科学分层、优化结构设计,很好地控制了大体积混凝土施工裂缝的发生和开展。
Hualong-1 nuclear power station is China’s third-generation nuclear power technology independently researched and developed. The strength of concrete in its containment has great significance to its own strength and public safety. As one of the important components of shield structure, Hualong No.1 basement not only undertakes the function of supporting structure , But also to prevent an important part of nuclear leaks, cracking of concrete requires higher. Hualong-1 multi-storey consolidation with the overall pouring construction technology to shorten the nuclear power project is of great significance, but the mass concrete construction of the anti-cracking technology needs further study. Based on the massive concrete foundation construction of the third generation nuclear power plant reactor building, the occurrence and development of cracks in mass concrete construction are well controlled through scientific stratification and optimization of structural design.
