The article deals with the prediction of deformation progress of the basement for a high-rise building founded in a deep foundation pit of 12.0 m below the ground level. Foundation consists of a stiff reinforcement concrete raft with basement in a Neogene layer of several ten metres. The deformation progress of the footing bottom is predicted by numerical approach of a finite-element method and the results are subsequently confronted with geotechnical monitoring. For this purpose, the input parameters were calibra...

At present many new housing projects are being realized in Poland. They are often built in areas characterized by complex hydrogeological and geotechnical conditions. In such cases, the need to build deep excavations is complicated, especially when there is a high water table. The paper presents analysis of dewatering process of deep excavation of residential building. The excavation was carried out to the depth of 10 m below the ground surface. Due to the location of the investment near the river the water table ...
