Konstantin Fedin, , Ph.D (Tech.), sr. research scientist of the Laboratory of Dynamic Analysis in Seismology spoke at the geophysical seminar of IPGG SB RAS. In his presentation he elaborated on a method developed based on extraction of standing waves from seismoacoustic noise for solving engineering seismic problems.

This method can be applied to a number of tasks, including: (i) diagnostics of buildings and structures and their structural elements; (ii) detection of underground voids; (iii) non-destructive testing (defectoscopy) for identifying flaws in metal and composite materials. The technique was tested during field works conducted at various sites located in permafrost and coastal area, near railroads – in conditions associated with the risk of reducing the stability of structures and buildings, i.e. where geotechnical challenges can be envisaged. Among the investigated objects were: residential and non-residential buildings, bridge supports, road pavement, and a lighthouse.


In particular, in-house IPGG SB RAS’ techniques allow monitoring the conditions of pipeline supports. The photo shows : a heating pipe main in Akademgorodok, Novosibirsk: sections of the pipes attached to the support with hard (a) and soft (b) joints; geophone and recorder (c)


– This research contributes to the understanding of possibilities of using passive seismic for examining fixity conditions of structures and foundations, thereby increasing reliability of results of passive microseismic monitoring of natural objects and man-made structures of different scale, - said Konstantin Fedin.

K.V. Fedin’s presentation prepared on the materials of his thesis for the degree of Doctor of Technical Sciences (DSc) (specialty 1.6.9 - “Geophysics”), aroused great interest among the attendees. Experienced colleagues gave him some valuable comments and recommendations which will be accounted for in preparation for the thesis defense.
