Scientific and Technical Justification of Geotechnical Solutions for Multi-Storey Dwellings Foundations Strengthening in the Event of a Roll

When constructing multi-storey dwellings in weak soils areas, the risk of a roll (the structure deviation from the vertical axis) is one of essential risks affecting operational reliability. The roll of a building maximum normative value is regulated by SP 22.13330.2016 “SNiP 2.02.01–83* Foundations of buildings and structures” and is assumed to be equal to i=0.004 H, where H is the building under study height. The case of a 16-storey dwelling with built-in commercial and public facilities construction in difficult engineering and geological conditions and in the presence of overlapping soils with weak dusty clay loams layers is considered. One of the building sections get the roll significantly exceeding the permissible values in accordance with the norms of SP 22.13330.2016. The analysis of the construction site engineering and geological conditions, the building structure features and the numerical modeling results of the changes in the base stress-strain state during construction is presented. The proposed and implemented methods of the damaged building foundation strengthening are analyzed. The results of the building foundations deformations monitoring are presented in comparison with the numerical calculation results.
