SAFETY MONITORING AND FORECASTING OF AN OLD LANDSLIDE SITE ON TONG-HUANG HIGHWAY

The GM(2,1) model for safety inspection and forecasting of a landsliding site is set up based on Gray theory. The anisochronous displacement is changed to the isochronous serial with Lagrange function. This model is used to the Chuang-Kou landslide observation site in Tong-Huang expressway. The results show that the GM(2, 1) model has higher forecasting precision than the GM(1, 1). The study shows that the landslide is safe after completion of treatment. This result agrees well with the actual situation.
