摘　　要：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。Based on the construction characteristics such as thin-layer Placement and continuousconstruction of Rolling Compacted Concrete(RCC) dam, the 3D FEM floating grid calculationprogramme is used to simulate the construction procedure and to calculate the temperature fieldand the thermal stress during RCC dam construction thereby revealing the changing laws oftemperature field and thermal stress in different transverse joints during the construction stagesas well as the maximum temperature stress of dam body in the case of same constructionconditions, which is of great reference value to RCC dam design.
