Physical basis of the remote monitoring method of pile foundations of building structures in permafrost areas

The article discusses urgent problems for the northern regions of monitoring the integrity of piles and parameters of the surrounding soil by seismoacoustic and electromagnetic methods and the tasks of remote monitoring for a long time. The possibility of controlling the piles by measuring the intrinsic resonant frequency of the borehole by the acoustic method and the parameters of the surrounding soil using temperature and humidity sensors with an estimate of the tangent of the angle of loss of electromagnetic fields at frequencies of 0.02–1 MHz is estimated.
