This paper describes the basic model of Kalman filter and its applications in deformation monitoring, introduces the general process and characteristics of the Kalman filter model in dealing with deformation monitoring data. Then a group of settlement data is processed by using the recursive formula to verify the filter effect. The data processing results prove that the Kalman filtering method suits for real-time processing of remeasurement data, can reduce random noise, improve the precision of the deformation monitoring data. When filtering algorithm is used in monitoring forecasting, the forecast data fits in well with the observation data, and the forecast data is believable.
