摘　　要：温度荷载是拱坝最主要的荷载之一,目前,通常采用计算常态混凝土温度荷载的方法计算RCC拱坝,这低估了温降的作用。以大花水电站拱坝温度荷载计算为例,对碾压混凝土拱坝的作用进行讨论,建议通过仿真分析方法确定封拱温度,在仿真成果基础上总结出一套计算RCC拱坝温度荷载的方法和理论。Thermal load is one of the main loads of areh dam, at present, the method of adopting thermal load of normal concrete in RCC arch dam calculation underestimates the action of temperature. The paper discusses the thermal action of roller compacted concrete arch dam from the experience of thermal load calculation in arch dam of Dahuashui Hydropower station, proposes to confirm closure temperature by way of simulative analysis, then summarizes a series of methods and theories of thermal load calculation of RCC arch dam on the basis of result of simulative analysis.
