FIELD: construction.
SUBSTANCE: method to measure subsidence of foundations consists of periodical measurement of position of mark arranged on foundation, relative to practically immovable benchmark. Position of mark at height is measured by sensor of linear displacements with converter of values of these displacements into electric signal relative to practically immovable benchmark, arranged under mark in soil below zone of soil freezing and zone of its deformation from foundation.
EFFECT: increased accuracy of measurement of building or structure foundation subsidence, provision of possibility of efficient monitoring online and for the whole term of operation, reduced material intensity of monitoring.
