摘要
万家寨大坝坝顶各监测点的变形过程是多峰曲线。文中采用物理推断和图表法分析了万家寨大坝的变形趋势!用广义线性多项式逐步回归方法建立了变形模型,并对大坝工作状况进行了初步分析,为大坝安全运行提供了依据。
The deformation process curve of the Wanjiazhai dam crest exhibits many peaks. In this paper, the trend of the
deformation of the Wanjiazhai dam is analyzed by means of physical deducibility and graphology, and a deformation model is
constructed with generalized linear polynomial stepwise regression. And then, the operation state of the dam is preliminarily
analyzed. The present work provides a reference for the safe operation of the dam.
