基于遗传算法的混凝土箱梁日照温度场的仿真分析

针对混凝土箱梁日照温度场仿真计算中材料参数难以准确取值的问题,建立了基于遗传算法的混凝土箱梁日照温度场计算模型。通过对某大型混凝土箱梁桥日照作用下温度场的模拟表明,该模型具有很好的适应性,虽然不一定能找寻出材料的真实性能参数,但可以较为准确地模拟日照辐射作用下混凝土箱梁的温度场。

Simulation Analysis for the Temperature Field of Concrete Box Girder Based on Genetic Algorithm

To solve the difficulty of selecting the material parameters accurately in the simulation analysis for the solar temperature field of concrete box girder,a finite model of predicting the solar temperature field of concrete box girder based on the genetic algorithm is established.By simulating the solar temperature field of one large concrete box girder bridge,the model was proved to be an effective model.The model has good adaptability and can simulate the solar temperature field of concrete box girder accurately,though cannot search the material parameters accurately.
