Khrapatova I. The Swelling soils at the multileveled basement for foundation plate and small buildings.

Subject - the swelling soils of Ukraine as a basement of buildings. Object - create method to estimate influence of swelling basement on joint work of system "basement - foundation -building" and also on work of separate construct element - foundation plate; Procedures - standard laboratory and field methods to investigate properties swelling soils and numerical FEM with applying program complex to analyse work of the system "basement - foundation -building" with swelling soils. Theoretical results - for the first time create method of preparation initial dates for calculation foundation plate on swelling soils has been created. The method uses coefficient "m" which has a lined dependence on density skeleton of soils and unlined dependence on vertical pressure; received a new decision for plate on elastic base, which allows to find the decision of contact task using FEM and take into account physical unlined dependences of swelling soils; applying program complex for flat task has been received a new method that takes into account joint work of system "basement - foundation - building" considering that some layers of soils are swelling soils; branch: constructional engineering.
