摘要
老采空区地基沉降和变形监测是沉降研究的可靠方法。基于监测数据进行沉降规律的分析和预测预报,指出了应用最普遍的统计方法即最小二乘回归分析方法存在的问题,应用稳健估计对含有粗差的沉陷数据进行了回归分析,得到了比较好的结果。
God groundwork subsidence and deformation monitoring is an inerrable method. The basic way basiced on monitor data in subsidence law analysis and predict forecast is statistics analysis. The most popular statistics method is least square regression analysis. The statistics data errors about least square regression analysis must conform to normal distriBution. Therefore this paper regression analysis the subsidence data which include gross error with the robust estimator and get good results.
