摘要
通过对某大坝坝基和相应水位的观测,得出坝基的沉降量与水位的变化有关系,并随机选取24组数据作为研究的起算数据,确定了两变量的回归直线方程,最后用回归直线预报相关的变形值,再加入一部分粗差进行稳健估计分析,求出稳健回归直线方程,对比并分析了两者的关系。
Through detecting the dam foundation and corresponding water level,the paper finds out the relationship between the dam foundation subsidence and water level change,randomly selects 24 sets of data as the original research data,determines linear regression equation of two variables,predicts relevant deformation value with linear regression,carries out robust estimation analysis by adding some gross errors,obtains robust linear regression equation,and finally compares their relationship.
