Abstract：Reestablishment of the initial condition for GM (1，1）mode was introduced in the paper.Firstly，characteristics of different initial condition for GM (1，1）modeling has been discussed，then，a rolling initial condition for GM(1,1）was established based on the fusion metabolic GM (1,1）and the principle of new information as first priority.Finally，RnGM was used to analyze and predict the deformation of surrounding rock in tunnels and subsidence of highrise building.Comparison of the model with other models shows that RnGM model is able to improve the precision of prediction and therefore can be applied to deformation data analysis.
