摘要
破开算子法是一种数值计算方法。本文把该方法应用于混凝土温度和温度徐变应力的计算,导出了计算公式,并给出了计算实例。文中既有非恒定问题;又有恒定问题、二者均获得了很好的效果。用此法计算不仅速度快,而且计算精度较高、程序简单。
The operator-splitting method is a numerical method. It is used to analyse the temperature field and elasto-creeping thermal stresses of mass concrete structures in this paper. Relevant formulas are derived and several numerical examples are given. Both nonsteady and steady problems are solved with good results. This method is faster in speed, higher in precision and simpler in procedure.
