基于回归分析的防洪大堤水平位移规律探讨

Discussion on horizontal displacement law of flood-control dyke based on regression analysis

针对防洪大堤施工中水平位移监测的研究现状和不足,文章通过防洪大堤水平位移及其影响因素的分析,建立了水平位移的回归分析初步方程,经过3次回归计算,得到了回归效果显著的回归方程。最后根据该回归方程进行水平位移预测实验,得到误差小于回归计算的2倍中误差的结果,表明该回归方程可以用于描述防洪大堤水平位移的变化规律。

Aiming at the insufficiency in the study of horizontal displacement monitoring in flood-control dyke construction, the paper built the regression analysis preliminary equation of horizontal displacement after analyzing the horizontal displacement and its influence elements. Through three times regression calculation, the regression equation with a marked regression effect was attained then. Finally, the hori- zontal displacement experiment was carried out according to this equation, the result showed that the error was smaller than double mean square error of regression calculation, which proved that the regression equation could he used to describe the horizontal displacement law of flood-control dyke.
