| Abstract: | Based on the Grey System Theory, the equal time interval of Gray model GM （1,1） and the modified metabolic model are used to predict the settlement beyond construction of bridge pile group foundation.The comparative analysis on the settlement observational material of YunZaoBang super major bridge proved that using grey theory prediction method on the post-construction sedimentation of bridge pile group foundation is feasible in practice. |
