摘　　要：利用三维有限元法,对桑郎碾压混凝土拱坝进行了全过程仿真分析.分析中考虑了混凝土绝热温升随龄期的变化、分层浇筑和夏季停工渡汛等影响因素,得出了温度场分布及其随时间的变化规律.The whole process simulation analysis of Sanglang RCC arch dam is done with 3D finite element method （FEM）. The factors, such as the change of adiabatic temperature with age of concrete, concrete placing by layer, work suspension on account of flood in summer, are considered in the analysis. The change laws of temperature field with time and its distributions are provided in the calculation results.
