土石坝流变非线性分析

采用流变学理论，选取Ｍａｘｗｅｌｌ模型和Ｈ＝Ｋ模型模拟土石料的流变特性，探讨土石料流变特性对土石坝应力、位移的影响，对梅溪混凝土面板堆石坝实例进行计算分析，结果表明考虑土石料的流变特性能更准确地反映土石坝施工期和运行期的实际工作性态。

Rheological Analysis of Earth-Rock Dams

On the basis of the rheologic theory,the Maxwell model and the H K model have been used to simulate the rheologic characteristics of rockfill materials,and the effect of the rheologic property on the stress and displacement of rockfill dams is also discussed.Finally,the Meixi concrete face rockfill dam is studied.The results show that the stress and displacement of the dam obtained are more reasonable when the rheologic property of rockfill material is considered.
