在叠加原理的基础上建立了混凝土徐变恢复函数，并利用恢复函数与徐变度函数建立了基于等效历史应力假定的双功能徐变函数，在各种变荷载情况下，对双功能徐变函数曲线与叠加原理意义下的典型徐变曲线进行了数值比较，结果发现它们的差异很小，能满足实际工程的需要。
Based on the principle of superposition, a reversible creep expression was derived. According to this expression, a double function creep model for concrete was established and contrasted with a common creep model through the numerical analysis under various loads. The results proved that the double function creep model can be applied in practice.
