METHOD OF DETERMINING RESILIENT CHARACTERISTICS OF GROUNDS OF FOUNDATIONS Russian patent published in 1994 - IPC

FIELD: building industry. SUBSTANCE: method comprises steps of applying dynamic loads to a foundation due to tensioning ropes, secured to opposite angles of the foundation at its lower mark up to a time moment of breaking the ropes; simultaneously measuring horizontal rotary motions, determining a factor of non-uniform elastic shift of grounds C_Ψ according to a mathematical relation C_Ψ=3P/a²A, where P-load at time moment of the rope breaking out, A - displacement of edge of the foundation sole; a - length value of a side of the foundation. EFFECT: enhanced accuracy and simplification of the method. 1 cl, 2 dwg
