【Abstract】 This paper briefly introduces the establishment and precision examination method of the GM(1,1) mod-el. Based on the characteristic that the pile top settlement changes with the load during the single pileplate load test, the grey prediction model of the single pile ultimate capacity was established. Moreoverby case histories, the grey prediction was conducted for the single pile ultimate bearing capacity.更多还原
