TECHNICAL SOLUTIONS TO PREVENT THE IRON OF A BUILDING UNDER CONSTRUCTION CAUSED BY UNPLANNED DEVELOPMENT OF FOUNDATION PROPERTIES

Abstract

In the process of designing buildings and structures - capital construction projects, all necessary surveys are carried out at the construction site, regulated by current regulatory documents. When choosing the type of foundation, the results of geotechnical surveys play a major role. The heterogeneity of engineering-geological strata, even within one specific area, can force designers to reflect in design solutions various methods of constructing foundations for residential buildings with the same loads and number of floors, including standard series. Performing calculations in modern software systems perfectly solves design problems. Based on the calculation results, it is possible to optimally select the material and cross-section of the main load-bearing structures, taking into account the requirements for operational reliability and durability. However, during the construction process, factors that were not taken into account during design may arise that can have a negative impact on the load-bearing capacity and subsequent operation of the facility. One such factor may be a sudden deterioration in the physical and mechanical properties of the soil base, caused by both objective and subjective reasons. At the same time, the construction of the facility is carried out above the zero cycle; the foundations and part of the floors have already been completed. The article provides examples of technical solutions to prevent the tilting of a multi-storey building under construction, caused by an unplanned deterioration of the properties of foundation soils, in the area of the village of Ostrovtsy, Ramensky urban district, Moscow region. The results of the work are given and analyzed. The causes of negative processes have been studied. The results of the study may be useful in the design and subsequent construction of modern buildings in similar conditions.
