According to the relation of landslide displacement time series

the stepwise inherited model is presented and applied to calculate the displacement and stable coefficient of every step for the landslide. Then the model is applied to Gushuwu landslide of Hu-Rong Expressway in Hubei Province. The results show that the displacement calculated by the model is perfect and this method is much easier to operate; and a new basis is presented according to the stable coefficient.
