摘要
采用三维非线性有限单元法对黄河公伯峡混凝土面板堆石坝施工填筑期和水库蓄水运行期的应力变形进行模拟分析 ,研究不同阶段坝体的应力变形 ,特别是面板的应力变形和“脱空”现象。计算结果较为全面地反映大坝的实际状况 。
In this article 3_dimensional nonlinear finite element method to analyse simulatively the stress and deformation of Gongbo gorge concrete_face rockfill dam on the Yellow River for construction and operation periods respectively are used to study the dam stress and deformation for different periods, especially the stress, deformation and renegade phenomena of the concrete face. The results generally reflect actual state of the dam and supply rational advices and effective measures for optimizing design.
