山口水电站区域气候呈大陆性气候,气候特征表现温和湿润,雨量充沛,昼夜温差大,夏热酷暑,冬冷严寒,春温回升迅速,秋温下降快等的气候,碾压混凝土大坝高51m,大坝碾压混凝土施工温控问题十分突出,是质量和进度控制的关键。为此,根据施工实际情况,介绍了该碾压混凝土大坝的温控要求,以及所采取的措施和效果。 Yamaguchi Hydropower Station regional climate was continental climate, mild climatic characteristics of climate performance, abundant rainfall, large temperature difference between day and night, hot and summer heat, cold and cold in winter, spring temperature rebounded rapidly, the fall in autumn temperature and other climate, RCC dam height 51m , Dam RCC construction temperature control problems are very prominent, is the key to quality and schedule control. Therefore, according to the actual situation of construction, the temperature control requirements of the RCC dam are introduced, and the measures and effects are taken.
