摘　　要：严寒地区碾压混凝土重力坝温控防裂难度大,早期裂缝较多,影响坝体结构的整体性和安全性。文章以新疆代尔昆代碾压混凝土重力坝为研究对象,在工程设计阶段开展温控防裂专题研究,针对施工过程中经历冬季停工难题,选取最高挡水坝段作为研究对象,开展温控措施的仿真计算,并给出温控防裂相关建议,为坝体温控防裂提供有力技术支撑。It is difficult to control temperature and prevent cracks of RCC gravity dam in severe cold area,and there are many early cracks,which affect the integrity and safety of dam structure.In this paper,Deir Kundai RCC gravity dam is taken as the research object,and special research on temperature control and crack prevention is carried out in the engineering design stage.Aiming at the problem of winter shutdown during construction,the highest retaining dam section is selected as the research object,and the simulation calculation of temperature control measures is carried out,and relevant suggestions on temperature control and crack prevention are given,which provides strong technical support for dam temperature control and crack prevention.
