堆石坝流变变形的反馈分析

本文中建议了一个比较简单实用的3参数模型，并通过4座已建坝的反馈分析确定了从软岩到砂卵石4种不同质地堆石料的流变参数，今后新建类似堆石坝时可以参考此值进行设计计算。

Back analysis of creep deformation of rockfill dams

In this paper a creep model with 3 parameters has been proposed for rockfill materials and it is emphasized that parameters are hardly can be determined from the laboraotry test because of the requirement of long duration. Four rockfill dams with different materials recently constructed in China have been analyzed with this model to get the model parameters through the comparison between measured and computed increments of displacement. Finally, four typical sets of creep parameters for rockfill material from very soft (mudstone) to very hard (granite) are recommended for design of rockfill dams.
