| Abstract: | Based on the grey theory,SGM(1,1) model of load-settlement relation for single pile is established and the way of using it to predict the integrated relationship of load-settlement and the ultimate bearing capacity of a single pile with limited measurement data introduced.The results of engineering cases prove that this method is reliable,and the precision of prediction can meet engineering need. |
