Tóm tắt:

In this study, the main objective is to predict accurately the consolidation coefficient (Cv) of soft soil using an artificial intelligence approach named Random Forest (RF) method. In addition, we have analyzed the sensitivity of different combinations of factors for the prediction of the Cv. For this, a total of 163 soil samples were collected from the construction site in Vietnam. These samples at various depth (m) were analyzed in the laboratory for the determination of clay content (%), moisture content (%), liquid limit (%), plastic limit (%), plasticity index (%), liquidity index (%), and the Cv for generating datasets for modeling. Performance of the models was validated using Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and Correlation Coefficient (R) methods. In the present study, various combinations of soil parameters were applied and eight models were developed using the RF algorithm for predicting the Cv of soft soil. Results of the model’s study show that the performance of the models using different combinations of input factors is much different where R-value varies from 0.715 to 0.822. The present study suggested that the RF model with an appropriate combination of soil properties input factors can help in better and accurate prediction of the Cv of soft soil.
