摘　　要：采用大型有限元计算软件与自主开发温度场仿真程序相结合，对某水电站厂房依照实际浇筑过程进行了温度场仿真分析，解决了仿真计算中混凝土跳仓浇筑的困难，通过与以前方案比较，说明浇筑方案对厂房温度场分布有较大影响，设计时可选择施工方案来降低温度。In this paper, a method of combining simulation computation program studied by independence with finite element calculation software is used to settle the difficulty in simulating three dimensional concrete sequence placement in complex mass hydraulic structure such as hydropower plant. With the method, we calculated and analyzed the temperature field of a hydropower plant. Comparing with the former scheme, we can conclude that the scheme of placement will have great influence on the distribution of temperature field and the different construction schedule can be chosen to reduce the concrete temperature field in the design of hydropower plant.
