中文摘要	根据水布垭面板坝实测变形,在试验参数基础上采用神经网络和遗传算法反馈得到堆石料的清华K-G模型参数,对大坝蓄水后的变形和应力进行分析。预测认为,正常高蓄水位下坝体最大沉降约为坝高的1%,面板最大法向位移约为457mm,应力状态表现为河谷部位受压,周边坝肩部位受拉,接缝体系的变形都在止水承受能力以内。; The direct back-analysis method combined with the neural networks and genetic algorithm is adopted to compute Tsinghua K-G model parameters of Shuibuya concrete face rockfill dam(CFRD) according to the measured settlement in Dec.2006. Tsinghua K-G model is used for 3-D FEM analysis to predict deformation and stresses when the water level reaches the normal high water level of 400m. The maximum computed settlement of rockfill dam is approximately 2.39m,which is only 1% of the dam height. The max normal displacement of face slab is computed about 457mm,and the result of stress analysis indicates that the face slab is compressed in central and otherwise around abutment. The displacements of vertical and peripheral joints are less than 5 cm within the capability of waterstop strips.
