| Abstract: | The DE-GM(1,1) prediction model of ultimate bearing capacity of single piles is established by using the DE algorithm to optimize the GM(1,1) parameters directly.The DE solution program is compiled based on Matlab,and an application of DE-GM(1,1) in prediction of ultimate bearing capacity of single piles is given.The results show that in comparison with the exponential curve model and the GM(1,1) model,the DE-GM(1,1) model fits the measured data better and makes prediction more accurately.Furthermore,the DE... |
