给出了用三参量流变模型研究止水橡胶粘弹性的基本表达式。结合某高水头闸门 止水材料的粘弹性试验，得到了所采用橡胶材料的流变参数，并指出了其蠕变变形和应力松弛变化的规律，为工程设计提供参考依据。

This thesis provided the basic expression formula for viscoelasticity of water-stop rubber based on the three- parametric rheology model.  Combining the viscoelastic test of some high-head gate water-stop materials,  the rheology parameter was achieved.  The thesis pointed out the laws of change of creep deformation and stress relaxation and offered the reference for engineering design.
