Abstract
Technical condition categories and their impact on additional deformations of buildings in the zone of new construction
Incoming article date: 04.02.2025The article considers the influence of the technical condition of buildings on their additional deformations in the zone of influence of new construction. As a result of the survey, it was confirmed that the buildings of the historical development of the III category of technical condition were in an unsatisfactory condition. In accordance with this, a numerical calculation was carried out, as a result of which an option for strengthening their foundations with the help of piles made using jet technology was proposed. According to the preliminary numerical calculation, additional deformations of buildings of the III category did not exceed the maximum permissible values. The adopted option of strengthening in this case did not justify itself and the actual deformations of the buildings turned out to be higher than the limit values already at the zero mark. Based on the monitoring data, it was found that the values of additional settlements are constantly growing in the process of erecting buildings of the multifunctional complex. Based on the calculation data, graphs were constructed illustrating the discrepancy between the actual additional deformations and the calculated values depending on the category of the technical condition of the buildings and their location in the zone of influence of the pit. Thus, when determining the zone of influence of new construction in close proximity to historical buildings, it is necessary to take into account their technical condition and operational safety.
