ABSTRACT
Basement deepening with floor construction represents a rational method of underground space development for installation of basement floors. In the presence of peat in soil, floor construction poses a difficult engineering problem. The article presents methods of floor construction for basement floors during reconstruction of buildings in the peaty territory of Arkhangelsk. Bored, driven, and jacked piles with a length up to 8 m are used in peat soils. Due to the long-term consolidation of peat, soil-supported “floating” floors are not constructed. Results of numerical simulation of piles using the PLAXIS 3D software allow obtaining “load/settlement” curves close to the data of full-scale static load tests.
