| Abstract: | Based on deep foundation pit of a subway station,the paper introduce the basic principle and calculation process of GM model of grey system.The GM(1,1)model was used to predict the piling deformation and subsidence of ground surface around the pit.By comparison of the measured value and the predictive value,the paper indicates that the predictive value can fit the measured value very well,and the accuracy is very high.It also proves that using the GM(1,1) model to predict the piling deformation and subsiden... |
