Abstract

The article presents the changes in the shape of karst sinkholes obtained in the course of modeling experiments during the joint operation of a cross-beam foundation bounded by a rigid vertical wall and an inclined base with a karst cavity. The regularities of transformation of the failure prism depending on the base inclination angle have been determined. The influence of the main variable factors was evaluated: the diameter of the karst cavity, the distance from the foundation footing to the center of the cavity, the distance from the center of the cavity to the retaining structure and the base inclination angle. Based on the results of model experiments, the values of the angle of deviation of the sinkhole formation from the vertical were obtained.
