【摘要】 热力学参数及边界条件是影响混凝土温控仿真计算精度的重要因素,而通过试验方式获得这些参数的成本较高,且往往与工程实际不符。引入模拟退火法,并对基本模拟退火法进行改进和分析。结果表明,改进的模拟退火法可以用于混凝土温度场的反问题研究中。更多还原

【Abstract】 Thermodynamic parameters and boundary conditions are the important factors for the simulation precision of concrete temperature control.And,the cost is higher,and the results are usually not conformed to concrete project,when the parameters are obtained by laboratory experiment.The simulated annealing is introduced,and the basic simulate annealing is improved and analyzed.The results show that,the improved simulate annealing can be used in the research of inverse problem of concrete temperature field.更多还原
