摘要
白石大坝是继观音阁大坝之后在北方严寒地区修建的又一座碾压混凝土坝（RCD），北方严酷的气候条件、间歇式的施工方法及碾压混凝上坝自身的特点，使其温控与防裂成为工程的一个重要课题．本文介绍了该坝的温度控制设计标准、防裂措施技术要求和仿真计算分析的主要结论；依据理论计算和实践经验，总结了大坝施工中为防止裂缝所采取的包括降温、保温、结构和原材料等一系列有效措施．可供北方严寒地区碾压混凝土坝进行温控、防裂提供借鉴和参考．
Baishi RCD Dam is another one constructed in northern cold region after Guanyinge Dam. Temperature control and crack-proof is very important in the project construction because of northern severe climate, intermittent construction method and the characteristics of RCD dam itself. This paper introduces thedesign criteria of temperature control and crack-proof measure requirements applied on Baishi Dam, and mainconclusions of emulating calculation and analysis. On the basis of theoretical calculation and practical experience, the paper concludes a series of effective crack-proof measures applied to construction such as loweringtemperatures, heat preservation, structure and raw materials. This paper is useful for reference in the aspect oftemperatrue control and crack-proof measures of RCD dam in northern cold region.
