摘　　要：给出了用微分型本构模型研究橡胶类止水材料粘弹性的三参量流变公式。结合止水材料的粘弹性试验分析了高水头作用下止水材料的粘弹特性对其止水效果的影响,并根据材料的应力松弛函数从理论上计算出三种止水材料的有效止水时间。该理论方法对橡胶类止水材料的粘弹性研究具有普遍意义,可以为实际工程提供科学有益的指导。The three-parameters rheology equation of viscoelasticity of rubber waterstop material is formulated by use of constitutive model of differential coefficient. Combining with the test of viscoelasticity of waterstop material, the influence of the waterstop effect of the viscoelasticity of waterstop material is analyzed when the flood peak is high. By means of principle of stress relaxation function of material, effectual waterstop time of three kinds of waterstop material is obtained theoretically. The equation is significant for viscoelasticity research of rubber waterstop material, and it can offer useful reference for pertinent practical engineering.
