根据碾压混凝土坝薄层浇筑、快速施工的特点，用三维有限元浮动网格法计算程序，对高碾压混凝土坝温度场和温度应力进行了仿真计算；揭示了不同横缝间距的坝体施工期温度场、温度应力和坝体最大温降应力的变化规律。该项研究对碾压混凝土坝设计具有参考价值。
According to the characteristics of thin-layer pouring and rapid construction of RCC dam, the calculation program of temperature field and temperature stress of RCC dam is carried out by using the three-dimensional finite element method of floating grid method. Variation of temperature field, temperature stress and maximum temperature drop stress during construction period. The research has reference value for RCC dam design.
