摘　　要：以典型溢流坝段为研究对象,模拟坝体施工过程,对大体积混凝土结构进行温度场与温度应力三维仿真计算,根据坝体混凝土温度场与温度应力分布规律,通过对温控防裂措施的敏感性分析比较,提出了典型时段和特殊部位混凝土温控防裂措施建议,为溢流坝大体积混凝土的温控设计及温控措施制定提供了依据。Considering the construction process,three-dimensional simulation calculation is carried out to study the temperature field and the thermal stress distributions of a typical overflow dam section in DG Hydropower Station.Based on the results of the temperature field and the thermal stress distributions of the dam body concrete,sensitivity analysis of different temperature control and crack prevention measures is then conducted.Suggestions are proposed on the temperature control and crack prevention of concrete in typical periods and special locations.The results provide useful basis for the temperature control design of the mass concrete in overflow dam sections.
