| 摘 要： | 依据碾压混凝土坝的材料特性，采用三维有限元浮动网格法对某碾压混凝土拱坝施工期至运行期温度场进行了全过程仿真分析。分析中考虑了混凝土的绝热温升随龄期的变化和分层浇筑、夏季停工及蓄水对坝体温度场的影响。计算成果给出了温度场分布及其随时间变化规律，为某碾压混凝土拱坝的设计和施工中采取相应的温控措施提供了参考。

| Abstract: | Based on the materials properties of rolled compacted concrete dam, three-dimensional finite element relocating mesh method is used to simulate the temperature field of a RCC arch dam from construction to operation period. The change of adiabatic temperature rise along with age and the effect on temperature field of dam body made by pouring lift by lift, work suspension in summer and water storage are considered in the analysis. The change laws of temperature field along with time and its distributions are provided in the calculation results, which offers the reliable basis for the corresponding temperature control measures taken in a RCC arch dam design and construction. |
