Contemporary geotechnical solutions for bases and foundations of emergency-deformed buildings-monuments on weak soils

Abstract

The tasks of strengthening the foundations of emergency deformed buildings and fixing the soil in their base during restoration and restoration work require engineering solutions that allow combining an increase in the bearing capacity of the base and the exclusion of the de-velopment of uneven deformations of the reinforced building. Such solutions are possible when using injection methods and the device of drilling-injection piles. The modern material for fixing the soils of emergency-deformed buildings is micro-cement Ultracement-5M and Polygel AFM-K3, which allow excluding the technological impact on the structures of the foundations of rein-forced buildings. The article presents the experience of strengthening the foundations of histori-cal buildings and monument buildings, as well as analyzes the accumulated experience in per-forming preventive strengthening of the foundation soils as protective measures in the presence of pits and underground structures under construction near buildings.
