| Abstract: | In this paper, according to features displacement-time curves the possibility to use acceleration as a factor of state identification is suggested and testified. In the stable cases, the prediction of the ultimate convergence displacements by means of GM(1, 1 ) model of grey system is discussed.In the unstable circumstances,the general formula of calculating unstable time with tangent angle is established. |
| |
| Keywords: | grey system prediction of stable displacement forecast of unstable time. |
