Review article

The article presents the results of geotechnical monitoring that determine the impact of work on the implementation of indentation piles and a deep spacer diaphragm manufactured by the jet cementation method on additional deformations of surrounding buildings. On the example of jet-diaphragm, there is presented a technique for modeling the «zero» cycle structures arranged in an array of soil without its excavation. Within the framework of the proposed methodology, the increase in pore pressure occurring at soil consolidation is ensured by the creation of lateral volumetric deformation in the soil mass, the magnitude and direction of development of which are determined by the specifics of the task. The obtained results of numerical modeling show convergence with the data of the in-situ geotechnical monitoring organized at the facility.
