The influence of the shape of high-rise buildings on the design features and methods of making foundations in difficult soil conditions

Abstract

The methods of calculation and design of foundations considered in the article are applied in the construction of high-rise buildings of complex shape in heterogeneous soil conditions, leading in each case to minimizing costs. Considered in the article multi-storey and high-rise buildings have a complex geometry, which is further complicated by the location of objects in particularly difficult soil conditions - on construction sites with a significant difference in the marks of natural relief, at risk of developing landslide processes, as well as seismic impacts with an intensity of 8-9 points. For each of the examples under consideration, the final technical solution of the foundations is described, which made it possible to minimize the totality of complicating factors. To achieve the result, original methods of staged construction of foundations were used, based on previously carried out full-scale tests. To confirm the reliability of the developed methods, geotechnical monitoring was carried out during the construction and operation of facilities. Further development of methods for designing foundations in difficult soil conditions will make it possible to achieve greater efficiency in the consumption of material for the construction of foundations and buried structures.
