中文摘要：
依据非线性弹性K-G模型理论对天池上水库面板堆石坝进行了应力变形分析。首先采用CAD图形和程序控制相结合方法建立坝体与地基模型，考虑了断层构造和岸坡变化，得到了较为精细的三维有限元模型。然后在模型计算中采用了施工逐级加载的方法对坝体进行了模拟，应用修正后的分级加载位移变形公式，对竣工期和正常水位蓄水期的应力变形进行三维有限元分析，得出了两种工况下断层对该高面板坝应力变形影响一般规律。
英文摘要：
The theory of nonlinear elastic K-G model was applied to analyze the stress and deformation of the concrete faced rockfill dam in Tianchi reservoir. The combination method of CAD drawings and program control was used to develop the model of the dam and foundation. The fault structures and bank slope change were considered in the model, and thus a more refined three-dimensional finite element model was obtained. The dam was simulated using the method of step-by-step loading, and the displacement formula of modified step-by-step loading was used to conduct three-dimensional finite element analysis of the stress and deformation during the completion period and under normal water level conditions. The effects of the fault structures on the stress and deformation of the high concrete faced rockfill dam were determined for the two working conditions.
