| Abstract: | The modified method of equivalent linear model was proposed when performing pile-soil-structure interaction. The dimension of near region was solved and the modified equivalent linear model was obtained. Then, the extensive numbers of the models were analyzed and the modified parameters were solved. Finally, the regression analysis was performed to obtain the empirical equation based on the extensive modified parameters. It is shown that the accuracy of pile soil structure interaction analysis under strong earthquake is improved with the modified method. |
