In the case of the present study, the three-dimensional PMWIN software was used, which is based on the finite difference method. A numerical modeling of the aquifer in the vicinity of the Bega canal where the component buildings of the ISHO study area are located was carried out. The modeling technique carried out allowed the numerical and hydraulic modeling of all types of sediments necessary to lower the water table in order to safely build constructions with a large foundation depth on the site, especially in the conditions of a significant groundwater supply due to the proximity of the Bega watercourse. Considering the complexity of underground hydraulic phenomena for which there are no exact calculation methods without simplifications, the only viable solution was the use of numerical modeling based on existing methods (element finite, boundary elements, finite differences); these modeling’s are difficult, especially regarding the calibration and validation of the numerical model. The presented method allows the optimization of the number of boreholes, respectively of the captured flows so that, with a minimum energy consumption and a minimum cost of the execution of the boreholes, it is possible to achieve the water level conditions necessary for the realization of underground constructions. |
