| Abstract: | On the basis of traditional technique,a new method is introduced for improving the precision of building subsidence observation.With this method,the inaccuracy of observed value,"angle i" and "variation of angle i" error,the error of different stadias between front and back,the effect of leveling staff offset plumb by illustrations can be avoid effectively,accordingly raising the precision of subsidence of construction observation is raised. |

| Keywords: | precise leveling building subsidence observation deformation monitoring subsidence survey point precision |
