Application of Grey Modal with Time-Varying Parameters Characters in Tunnel Surface Settlement
Tiesheng Wang · Water Resources and Power · 2006
Based on the analysis of the tunnel construction process and the shortcoming of the classic grey model,a new prediction method with bivariate polynomial a(t) and b(t) is proposed.Not only the spatial character but also the time-varying character are considered,and the forecasting precision of underground settlement is effective in the practical application.
