The Influence of the Device of Deep Pits on the Bearing Capacity and Deformation of Pile Foundations of Surrounding Buildings

The article deals with the issue of the influence of the open pit construction on the nearby pile foundation of the surrounding buildings (existing or designed as protective measures). Within the framework of this work, computational schemes with a single pile located within (scheme 1) and below (scheme 2) the boundaries of the collapse prism were considered, as well as available pile modeling tools were analyzed. Based on the results of numerical experiments, conclusions are drawn about additional vertical and horizontal displacements, friction forces and internal forces. There is a significant transformation of the scheme of the foundation and the emergence of negative factors that reduce the margin of reliability of the structures under consideration. The question is raised about the need to develop a methodology for taking into account the phenomena considered and fixing special requirements for design and calculation in the norms.
