FIELD: construction.
SUBSTANCE: method includes foundation excavation with uncovering of grillage foot, alternating execution of two slots from side of opposite corners of the cross section of the pile shaft with installation of flat jacks in them, cutting of fittings in two other corners of the cross-section of the pile shaft, separation of pile from grillage by stretching the remaining concrete section of the pile shaft by means of jacks, static testing of pile by indentation with measurement of its movements. Method permits to determine the load-bearing capacity without interrupting work of the pile being tested and without reducing the load on it and not allowing movements, usually occurring when the load is removed. Stress state of soil mass holding the pile, that was formed during operation of foundation, remains unchanged.
EFFECT: increasing the reliability of determining the load-bearing capacity.
