To ensure the safety of constructions such as bridge-owned structures, they must be immunized for the operational period. Considering the Pile settlement (PS) factor has to be an important project issue, much attention is paid to prevent damage before construction. Various items are considered to evaluate the movement of the piles that certainly help to understand a future picture of the project over the loading period. Most intelligent mathematical strategies in calculating the pile motion are operated. In this regard, the present research has used a machine learning technique: support vector regression (SVR). As a novelty of this research, two optimizers were used to find the key variables of SVR at optimum level to fine PS accurately. Biogeography-Based Optimization (BBO) and Flow Direction Algorithm (FDA) were coupled with SVR to create the SVR-FDA and SVR-BBO frameworks. Moreover, several metrics have been used to assess the overall performance of models. The R2 of the training phase for SVR-FDA was found 99.39 percent shows a great modeling process, while the RMSE of this model was calculated 0.4286 mm. The OBJ index as a comprehensive indicator including MAE, RMSE, and R2 was obtained 0.2499 mm.
