摘　　要：从Perzyna弹粘塑性本构模型出发,考虑混凝土材料的损伤,推导提出了混凝土弹粘塑性损伤本构模型,通过与相关文献所列实验数据比较,验证推求了所得模型的适用性,指出该模型能够反映出混凝土材料不同的拉压性能、混凝土材料的应变率敏感性、静水压力及中间主应力的影响,具有一定的实用价值。From the Perzyna viscoelasto-plastic constitutive model, considering the damages of concrete material, this paper deduced the concrete elastic viscoelasto-plastic damage constitutive model, through the related documents listed experimental data comparison, verified the applicability of calculation model, pointed out that the model could response the different tensile and compressive properties of concrete material, the strain rate sensitivity of concrete material, the influence of hydrostatic pressure and intermediate principal stress, had certain practical value.
