| 摘 要： | 结合龙滩碾压混凝土重力坝工程实例,模拟薄层浇筑时大坝的温度场变化,通过成层浇筑大体积混凝土的一维温度场计算对比分析,得出对类似工程设计和施工有益的建议,即可用有限单元法模拟成层浇筑混凝土温度场,与理论解差分解相结合,更好地应用到大体积混凝土施工过程的仿真计算中去。

| Abstract: | Combining the project case of Longtan roller compacted concrete gravity dam and the change of the dam temperature field when simulating thin-layer pouring. The article conducts a comparative analysis of massive concrete temperature field calculation of one dimension for stratification pouring, which contributes to worthwhile guidance and suggestions for project design and construction of similar types. The finite element method can be used to simulate layered pouring concrete temperature field in combination of theoretical decomposition so that it is better applied to simulation calculation in massive concrete construction. |
