土石料的流变模型及其应用

A creep model of rock-fill material and determination of its parameters by back analysis

摘要: 文中提出的三参数流变模型，与笔者原先提出的双屈服面弹塑性模型相配合，可用于土石坝的变形分析。通过反馈分析求得流变参数。还利用湖南省株树桥面板堆石坝的原型观测资料进行了计算。

Abstract: or coarse granular materials it is difficult to study its creep behavior in laboratory.In this paper a simple creep model with only 3 constants is proposed and a methodto determine those constants by back analysis is suggested. By using observedmovements in Zhushuqiao concrete faced rock-fill dam a set of constants for soft rock-fill like brocken shale as used in this dam is obtained.
