| 摘 要： | 提出确定性模型温度分量的合理表达式，即基于数理统计和温度场理论，首先建立求解坝体运行初期温度场的计算模型，再由温度场计算温度应力分量，进而建立改进的应力确定性模型。分析表明，改进后的应力确定性模型比常规模型拟合精度高，且易于预报。

| Abstract: | The fitting precision of the deterministic model is theoretically the best.But it may produce opposite result,if treated improperly.Based on mathematical statistics and the method for setting up temperature field,a computation model of the temperature field in initial stages is established first,the component of temperature stress is calculated,and all improved deterministic model is established.Analysis shows that the precision of the improved deterministic model is better than that of the conventional model and is easy to forecast. |
