钢筋混凝土面板堆石坝面板应力应变研究

Research on Stress and Strain of Concrete Face Rockfill Dam

本文结合碾压堆石坝的工程特性,修正了用有限元法求解坝体应力应变时的不合理初始条件,用邓肯-张非线性弹性E-v模型,通过对一理想坝型的计算,着重探讨了钢筋混凝土面板堆石坝坝体的变形和面板的变形、应力。

Based on the engineering characteristics of roller-compacted rockfill dams, the unreasonable initial condition in the analysis of the stress and strain for these rockfill dams is modified in this article. The displacement and stress of an ideal concrete face rockfill dam are investigated with Duncan-Chang's non-linear elastic E-v model. Satisforctory results have been obtained.
