Abstract :
The the deformation of the building is regarded as the function of the time and excavation depth of the foundation ditch in the paper, and Taylor series is used to erect the functional relationship of the building deformation to the time and excavation depth, 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 Kaman filter model and predict the deformation of the building. An example of calculation shows that the fitted effect and forecast effect of the model are better.
