Abstract

Abstract

The application of gray system theory in the settlement pr ediction of roadbed foundation is discussed.Some improvements on the restrictive equal model GM(1,1) are made and the nonrestrictive unequal inter val model is built.With the help of practical projects,the prediction results of the two kinds of models are also compared,it’s showed that the improved GM(1,1) has been more effective,suitable,and the out-come precision can meet the practical need even more.
