ENGINEERING GEOLOGICAL AND HYDROGEOLOGICAL CONDITIONS AND METHODS FOR DRAINING AND CONSTRUCTING BUILDING FOUNDATION NEAR A WATER BASIN

ABSTRACT. The terrain in which the construction is carried out is built of weak soils. The level of ground water reaches the land surface. This requires lowering of the ground water level and constructing the foundation of the building in adverse engineering geological and hydrogeological conditions. Thus, small diameter vertical drains located along the perimeter of the drained area are used. This article presents the calculations for dimensioning small diameter vertical drains. Their flow rate and the corresponding depression curves have been investigated thoroughly. Аn engineering geological way to overcome the complex construction conditions in relatively weak soil varieties is offered. Due to the low values of soil deformation and strength parameters, the application of pile foundation is planned. The piles are designed and distributed according to the loads from the main construction. In this way, the safety of the building construction is guaranteed with appropriate technology.
