According to the series-wound and shunt-wound principle ot composite material and equivalent deformation, the calculation formulas for determining the viscoelastic parameters of the effect zones for RCC dam are derived. Furthermore, .the method of back analysis of the viscoelastic parameters of the effect zones is put forward based on back analysis method of synthetical viscoelastic parameters and study of the corresponding experimentations. The case study shows that the method is feasible and can preferably apply to determining viscoelastic parameters of the effect zones.
