One of the consequences of the construction in the conditions of dense housing system is the development of underground part of buildings, which influences the surrounding buildings, changing the stress-strain state of soil masses and hydrogeological conditions of the construction site. The damming effect leads to local increase of hydrostatical pressure of ground waters on underground structures. The authors present a description of hydrogeological conditions of the construction site of underground construction and mathematical geofiltration model of the soil foundation. The results of numerical investigation of the change in the hydrogeological mode of the construction area in case of enveloping the foundation pit with the wall in the ground are considered. On the first stage the basic mathematical model was calibrated by variation of the values of geofiltration parameters of water-bearing sediments and water-resistant mass and the values of infiltration recharge. The validation criterion of the mathematical model was the good agreement of the modeled and real ground water levels obtained as a result of compilation of the existing geological and hydrogeological materials. The construction simulation was carried out in a multivariant formulation for the conditions of entirely impenetrable wall in the ground with the filtration coefficient 0.001 m/day.
