【摘要】 用二维非线性有限元法分析了混凝土面板堆石坝的应力变形特性，并对堆石料进行了灵敏度分析．用邓肯 Ｅ Ｂ 模型作了应力、变形分析，得到坝体变形、面板变形和应力等成果．在此基础上得到了重要的结论，即参数的变化对位移影响很大而对应力影响很小．对堆石料需进一步研究的问题进行了讨论．更多还原

【Abstract】 dimensional finite element method is used to analyse the concrete face rockfill dam stress strain characteristics and the sensitivity of rockfill materials is analysed.Through a numerical illustration of calculations using Duncan E B model,the analysis is tested.The conclusions derived from the application of that model are presented.Finally the problems worth deeper study in the future are discussed.更多还原
