中文摘要：
堆石体存在流变，不仅与荷载有关，而且与干湿循环有关．堆石坝的长期变形观测资料表明，雨季产生的变形常显著高于非雨季、因此，研究堆石料长期变形时需分别考虑荷载作用和干湿循环所产生的流变规律．通过室内试验分析了仅考虑荷载作用的堆石流变特性，重点是应力状态对流变的影响．试验结果表明，荷载作用下堆石流变随时间呈衰减趋势，符合双曲线形式，最终体积流变和剪切流变与应力状态有关．
英文摘要：
Creep deformation of rockfill has relations with not only load but also wetting-drying cycle. According to rockfill dam long-time observation, it is also indicated that deformation in rainy seasons is obviously greater than that in other seasons. The deformation caused by load action and wetting-drying cycle should be studied respectively in rockfill long-time deformation research. A creep test only considering load effect is done to study the effect of stress condition on rockfill creep. It shows that creep deformation reduces with time and can be described by hyperbolic curve. Final volumetric and shearing creep deformation has relations with spherical stress and stress level respectively.
