摘要
在大体积混凝土温度场仿真计算中,热力学参数通常由试验或经验公式获取,与现场实际可能存在较大的出入.根据施工现场获取的实测温度数据,利用基于遗传算法编制的反演分析程序对某混凝土拱坝的热力学参数进行反演分析.通过实例证明:遗传算法在混凝土热学参数反演分析求解中简单通用、适应性好且求效率高.
In the simulation of concrete temperature field, the thermal parameters which are usually acquired by the experiment or the empirical equation may not always consistent with the actual situation. Basing on the actual temperature data measured in the field,back-analysis program is used which is based on the genetic algorithms to back analysis the concrete thermal parameters of a arch dam,good result is achieved. As one kind of optimization methods,the genetic algorithms is simple and universal, and also has the characteristic of good adaptability and high efficiency.
