A.V. Spirin, A.S. Grishina

At the present time it's necessary to modernize existing buildings. The purpose of this article is review and comparison of reinforcing technologies of foundations during building reconstruction. Superstructure of existing buildings often causes the need to expand the foundation base or reinforce the soil base. The article presented modern technologies of reinforcing of foundation on clay soils that are common in Perm. Described methods main features, advantages and disadvantages are examined. As an example calculation of additional vertical deformations of foundation of the existing secondary school building in Perm for various reinforcing methods of its foundations in PLAXIS software package is produced. The results of the technical and economic comparison of the various reinforcing methods are presented. Equal effectiveness of foundation base expansion, use of injection piles and the electrochemical anchoring of the ground base is demonstrated.
