在以往建模方法的基础上，对水压分量计算时隐含的约束条件进行了剖析，提出了用实际温度场计算温度分量的方法，考虑了应力对时效分量的影响，用迭代法确定了θ的大小．实例分析表明，本文所建立的模型和计算方法更能反映实际情况，精度可提高约３％．
Based on the previous modeling methods, the constraints implied in the calculation of hydraulic components are analyzed. The method of calculating the temperature components with the actual temperature field is proposed. The influence of stress on the aging components is considered. The iterative method is used to determine The size of θ. The case study shows that the model and calculation method established in this paper can better reflect the actual situation and improve the accuracy by about 3%.
