九甸峡混凝土面板堆石坝三维流变分析研究

he rheological behavior is one of the important characteristics of the rockfill, which has a great influence on the stress and deformation of the dam and concrete face. In this paper, by use of the different rheologic models, through simulating the construction process and the impound process, the long-term deformations of the embankment and concrete face after running for ten years are predicted and analyzed, and the variation laws of the deformation of dam and concrete face under the rheological condition are compared with the one without rheology. It is concluded that the influence on the arching effect of dam caused by the rockfill rheology is not obvious. The working behavior of the dam is predicted preferably, which provides theoretical reference for the design, construction, operation and maintenance for the dam.
