| Abstract: | To improve the prediction accuracy on the soft foundation subsidence model, the paper puts forward L-V model which is superposed on the existing Logistic model and Von-Bertalanffy model, and takes advantage of the Origin fitting software to solve the model parameters. The model is applied to soft foundation subsidence prediction compared with the Logistic model and Von-Bertalanffy model. The results shows that predicted fitting degree of L-V model is highest to 0.997 8; the L-V model average root error (RMSE=1.512) of settlement later is less than that of Logistic model (RMSE=2.930) and Von-Bertalanffy model (RMSE=3.624), and the prediction is approximated to the observations. |
