摘　　要：基于三峡大坝关键监测部位——泄2号坝段实测坝顶水平位移较大的情况,对其在初期蓄水及运行过程中水平位移变形性态进行了定性分析,并结合统计回归模型进行了变形原因分析。结果表明,泄2号坝段结构和工作性态正常,为三峡大坝安全运行提供了依据。Concerning of relatively big horizontal displacement of the crest of flood sluicing section 2, which is the vital position of Three Gorges dam, the deformation behavior for horizontal displacement during the initial water storage and operation process is qualitatively analyzed. And the causes of the deformation are analyzed through a regression model. The result shows that the structure and behavior of flood sluicing section 2 is normal, and provides reference for safety operation of Three Gorges dam.
