| Abstract: | This paper combines characteristics of the grey computation model and the initial stress field of rock masses, presents establishment methods of the grey model of the initial stress field and accuracy prediction, and applies GM (0,3) model to the initial stress field regression of the Jining first-class hydropower station foundation site. The computation result shows that the grey model has better regression effect than boundary displacement adjustment. |
