Considering that the deformation of Lianziya Hazardous Rock Mountain is influenced by the temperature obviously,the deformation of Lianziya Hazardous Rock Mountain is regarded as the function of the time and the temperature in the paper,and Taylor series is used to erect the functional relationship of the deformation to the time and the temperature,the remainder term of Taylor series and the variation of coefficients of second power of the variation of the time and second power of the variation of the temperature are regarded as dynamic noises whose mathematical expectation are 0 to erect Kalman filter model and predict the deformation of Lianziya Hazardous Rock Mountain.An example of calculation shows that the fitted effect and the forecast effect of the model are better.
