PECULIARITIES OF DESIGN OF VERTICALLY REINFORCED BASE OF SLAB FOUNDATIONS

The analysis of experimental and theoretical studies of reinforcement of soil foundations to create an artificial foundation on weak soils is given. The aim of the present work is to develop a design solution of a vertically reinforced base of a slab foundation of a multi-storey building. The study is carried out on the example of the design solution of reinforcement of the foundation of a real object. The novelty of the work consists in determining the optimal parameters of the reinforcement grid and the length of reinforcement of the soil mass to ensure the bearing capacity and reduce the settlement of the slab foundation base. Numerical calculations were carried out by the finite element method using the PLAXIS 3 programme, using the Hardening Soil model, in accordance with the requirements of Eurocode 7. Reinforcement of the soil foundation with rigid vertical reinforcing elements increased the bearing capacity of the foundation and reduced the settlement by 2 times. The use of rolling equipment in the construction of bored vertical reinforcing elements is a promising and reliable method of ensuring the bearing capacity and deformability of the foundation, which significantly reduces the time and costs required for the creation of artificial foundations.
