Technical solutions to prevent the roll of the building under construction caused by unplanned deterioration of the properties of the base
In the process of designing buildings and structures - capital construction objects, all the necessary surveys are carried out on the construction site, regulated by the current regulatory documents. An important role in choosing the type of foundations is played by the results of the performed engineering and geological surveys. The heterogeneity of engineering and geological strata, even within one specific site, can force designers to reflect in design decisions different ways of laying foundations for the same loads and number of floors of residential buildings, including standard series. Performing calculations in modern software systems perfectly solves design problems. Based on the results of the calculations, it is possible to optimally select the material and cross-section of the main load-bearing structures, taking into account the requirements of operational reliability and durability. However, during the construction process, there may be factors that are not taken into account during the design, which can have a negative impact on the load-bearing capacity and subsequent operation of the object. One of these factors 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 object 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 roll of a multi-storey building under construction, caused by an unplanned deterioration of the properties of the foundation soil, in the area of D. Ostrovtsy of the Ramenskoye city district of the Moscow Region. The results of the work are given and analyzed. The causes of negative processes are investigated. The results of the study can be useful in the design and subsequent construction of modern buildings in similar conditions.
