Influence of the Parameters of Karst Dips on the Stress-Strain State of the Structures of the Pile Belt Foundation
Abstract: In this paper, constructive protective measures of buildings and structures in karst-dangerous territories are considered, in the form of pile foundations joined by a tape monolithic grillage. Numerical studies were carried out using the Plaxis 2D software package to determine the maximum geometric dimensions of the karst cavity, in which no collapse of the overlying layers of soil. Then with the help of the LIRA PC, the influence of the change in geometric parameters and location in the building plan and on the depth of the base of the karst cavities on the stress-strain state (VAT) of the pile foundation foundation constructions has been determined. The VAT study of the foundation construction showed that the most unfavorable is the case when the karst cavity is located along the lateral surface near the heel of the pile in the center of the grillage.
