中文摘要：

对两河口水电站混合料进行了三轴流变试验研究,对其流变机理和模型进行了探讨。两河口水电站混合料的轴向和体积流变特性可以用幂函数来描述,模型参数可根据试验得到的流变特性确定,并对流变模型参数的影响因素及取值进行了分析。

英文摘要：

The rockfill creep behavior of Lianghekou dam is studied through triaxial creep tests.The rockfill creep mechanism and the creep model are discussed.Power function appear to represent the axial and the volumetric creep behavior reasonably well.The parameters of the model could be achieved by the triaxial creep test,and the factors affecting model parameters are analyzed.
