摘　　要：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％．On the basis of previous mathematical model formulation,the restraint condition hidden in the calculation of hydraulic pressure component is analysed,the method for determining the temperature component with practical temperature field is proposed,the influence of stress on time effect is considered and the value of θ is determined by interation method.A real example analysis shows that the actual situation could be reflected by the present mathematical model and calculating method and the precision is increased by about 3%.
