摘　　要：100m以上薄碾压混凝土拱坝采取整体碾压的施工方式,内部温度受外界气温和水温变化影响敏感。因此,其在发热过程及温度变化规律等方面均较独特。通过三维有限元瞬态温度场仿真分析,得到了某100m级薄碾压混凝土双曲拱坝从施工到运行全过程温度场变化规律,为该工程的温控措施设计和控制温度应力提供了依据。Inner temperature of 100m thin RCC arch dam is sensitive to the change of outer air and water temperature, and it has unique features in heat generation process and changing law of temperature. By 3D FEM transient simulation analysis of temperature field, the law of temperature field change of the arch dam in the whole process from construction to operation is found out , providing basis for design of temperature control and control of temperature stress in this project.
