摘要
针对佛子岭连拱坝垂线改造前后坝顶水平位移实测资料进行分析,分别对新、旧两套垂线系统所测水平位移建立各自的回归模型。深入分析了佛子岭连拱坝的变形性态及变形规律,结果表明:坝体变形主要受温度的影响,水压和时效的影响较小;高水位、低气温、高水温是连拱坝变形最不利的荷载工况。
In this paper, according to the observation data of horizontal displacement in the period of the rebuilding of plumb, the deformation law of Fuziling Multi arch Dam is analyzed. The regression models are given respectively based on the system of the new plumb and the old one. The deformation behavior and law of Fuziling Multi arch Dam is deeply researched. The research results showed that the deformation of the dam is effected more by temperature than by hydraulic pressure and time. The most disadvantageous loading condition of the deformation of multi arch dam is of high water level, low air temperature and high water temperature.
