通过对黄河天桥水电站混凝土坝段位移原型观测资料的跟踪分析，表明跟踪分析并不仅仅是将后期的观测资料简单的代入根据前期资料所建立的回归方程。简单的代入不可能对坝体后期的结构性态作出全面准确的评价。正是通过对天桥水电站混凝土坝段位移的全过程分析才发现该坝段后期出现向下游转动的异常现象，并揭示了Ｏ１１２层承压水过量抽取对坝体结构性态的影响。
Through the tracking analysis of the prototype observation data of the concrete dam section of the Yellow River Tianqiao Hydropower Station, it shows that the tracking analysis does not simply substitute the later observation data into the regression equation established according to the previous data. Simple substitution can not make a comprehensive and accurate evaluation of the structural state of the post-dam. It is through the full analysis of the displacement of the concrete dam section of the Tianqiao Hydropower Station that the anomalous phenomenon of the downstream rotation of the dam section is found and the influence of over-pumping of O112 layer on the structural behavior of the dam body is revealed.
