2、ersity,Wuhan 430079, China)Abstract: Curve fitting is a commonmean in deformationmonitoringdata process. This paper took the sedimentation deformationmoninulltoring of a talldwelling house in JiNan as an example. Firstly, it introduced the project of the deformation monitoring. Then adopt lognullari
3、thm model to curve fitting themonitoring data after comparingwith othermodels, according to the characteristicof sedimentation denullformation of tall buildings, and predicted the sedimentation deformation by programming based onMATLAB7. 0. Finally, the advantageof themodel is explicated.Key words:
