摘要
为了获取南水北调工程高性能混凝土准确的温度场边界条件,浇筑了一个大型混凝土试块,其中通有3根不同的塑料冷却水管,试块四周和底面采用了5种不同的模板,上表面覆盖了4种不同的保温材料.采用遗传算法对实测数据进行反演,获取了相关的边界条件参数,对温控仿真计算具有重要的参考价值.
A large concrete test block is created to get the exact temperature field boundary condition of high performance concrete for South-North Water Transfer Project. Three different plastic cooling pipes are disposed in the block. Five different kinds of molding boards are used on the surround and bottom surfaces. Four different kinds of insulation materials are covered on the top surface. According to the tested data, the corresponding boundary condition parameters are inversed by genetic algorithm. It will provide important reference to temperature control simulation.
