摘　　要：针对青铜峡大坝２４号和２５号坝段的不寻常变形性态，运用多种模型和方法分离了其主要影响量。在此基础上，对Ｆ５，Ｆ６大断层以及坝基扬压力产生的时效，及其对上述两坝段变形的影响作了综合的研究分析。由此，基本弄清了上述坝段变形的物理成因。Based upon the anomalous deformation behavior of No 24 and No 25 blocks of the Qingtongxia dam,this paper detaches the main factors from various affecting factors with various models and methods.Then the time effect of the large fault and dam base uplift and its influence on the deformation of the two blocks are comprehensively analyzed and studied.The physical factors leading to the anomalous deformation are found out.

关 键 词：大坝 变形性态 多种模型 综合分析
