针对堆石料蠕变的力学特性，采用大型高压三轴蠕变仪，对两河口堆石坝堆石料进行了蠕变试验。试验在常规等围压加载方式的基础上，采用了等应力比加载方式，并对堆石料蠕变试验的结果和加载方式进行了讨论。结果表明采用等应力比加载方式，堆石料变形更接近堆石料实际蠕变过程。

According to the mechanical properties of rockfill material creep, the large triaxial creep apparatus with high pressure is used to carry out the creep test for Lianghekou Dam' s rockfill materials, which adopts the equivalent stress ratio loading mode based on the routine confining pressure. Through the experiments, the results of the rockfill creep test and its loading mode are discussed in detail. The experimental results show that by taking the equivalent stress ratio loading method, the deformation of the rockfill material is more close to the actual process of the rockfill creep.
