摘　　要：温控防裂是碾压混凝土坝的核心问题之一。利用三维有限元法,对亚碧罗碾压混凝土重力坝施工期温度场进行仿真计算;计算中考虑混凝土绝热温升随时间的变化、通水冷却、分层浇筑和气温环境的变化等因素,得出了亚碧罗碾压混凝土重力坝温度场分布及其随时间的变化规律。One of the principal problems in construction of a RCC dam is the temperature control and crack prevention. In this paper the temperature field simulation analysis of Yabiluo RCC gravity dam is done with 3D FEM. The factors such as change of adiabatic temperature rise with age of concrete, water pipe cooling, placing concrete in layers and change of environmental temperature are considered in the analysis. The laws of temperature field distribution of Yabiluo RCC gravity dam and its change with time have been obtained.
