| 摘 要： | 根据面板堆石坝的变形特性和原理,采用分段拟合法,以2条不同的回归曲线分别拟合面板堆石坝施工期、运行期的沉降,建立相应的统计分析模型;根据白溪面板堆石坝垂直位移实测数据,以单纯形法和线性回归两步交叉进行统计回归分析,取得了较高精度的结果.综合分析认为,白溪面板堆石坝累计沉降量相对较小,垂直位移变形基本收敛趋于稳定.

| Abstract: | According to the deformation characteristics and principle of CFRD, the sectioned fitting method is used to build statistical analysis models for the construction stage and operation stage of CFRD with two different regression curves. The vertical displacement data of Baixi CFRD are analyzed with the simplex method and linear regression two-step cross method, and high accuracy is achieved. Synthetical analysis indicates that Baixi CFRD has a relatively small cumulative settlement, and its vertical displacement deformation is basically convergent and stable. |
