METHOD FOR DEFLECTED GROUND MODE DETERMINATION AT BUILDING STRUCTURE BASE Russian patent published in 2007 - IPC E02D1/00 

FIELD: construction, particularly to determined mechanical-and-physical ground properties for motorcar and oil-and-gas facilities design and erection in difficult geological engineering conditions.

SUBSTANCE: method involves determining mechanical-and-physical ground condition at building structure base by installing pressure sensors at structure base; measuring main stresses at building structure base; outlining active deformation zone at building structure base and calculating deflected mode characteristics with the use of Lode parameter for deflected mode type determination. Another zone corresponding to maximal cube volume and shape is outlined by pressure sensors. Cube faces are used for mean main stresses determination, as well as deflected mode type and deflected mode tension value calculation.

EFFECT: increased efficiency.
