Abstract
The choice of the foundation type is a crucial issue for ensuring safety and reliability in the construction of buildings and structures of various levels of responsibility. The main advantages of the construction of man-made bases are both their operational properties and the cost-effectiveness of the construction. At the same time, in case of exceeding settlements the reinforcement of soil base allows to reduce them. The paper presents the formulation and solution of the problem of behaviour of the stress-strain state (SSS) in the system «reinforcing elements – surrounding soil» on the example of a 21-storey building with a height of 65.7 m. Finite-element modelling related to the application of reinforcement elements of various parameters such as length, stiffness and geometry, as well as conventional methods of foundation construction such as slab or pile foundation. Analysis demonstrates that reinforcement elements have significant variability and could be effectively used in cases where the installation of a slab foundation settlements exceeding ultimate values. In addition, it shows which geometry of reinforcement elements is relevant to rational application in terms of settlements and forces in such elements.
