摘要
结合某大坝实测数据进行分析,对变形监测数据分别采用经典最小二乘平差、标准Kalm an滤波、方差补偿自适应Kalm an滤波3种方法进行处理,并用M atlab软件编制了数据处理程序,对方差补偿自适应Kalm an滤波数据处理结果进行验证。通过比较分析得出,方差补偿自适应Kalm an滤波数据处理结果能较好的满足工程需要。
This paper combined with the deformation monitoring data of the Dam Project,uses three kind methods of the classical least squares,standard Kalman filtering,and self-adaptive Kalman filter variance compensation to carry on data processing,and with the Matlab software compiles data processing program,verifies the results of compensates self-adaptive Kalman filter data processing.Through the comparative analysis,to get the conclusion of self-adaptive Kalman filter variance compensation data processing can meet better the needs of the project.
