Abstract
A new approach is suggested that enables detailed seismological engineering investigation of buildings, bridges, dams, etc. by the method of standing waves using small-channel instruments. Recalculation of standing waves from one point to another, which is possible to a predetermined accuracy, allows simultaneous recording of standing waves on networks of points of any density from microseismic records obtained at these points at different times.
Specific features of observation systems and standing waves recalculation algorithms are considered for various types of structures.
Experimental data show that the new method has high potentialities for detection and detailed investigation of standing waves in engineering structures. Investigation of the geometry of standing waves and spatial distribution of phases provides information on the physical state of the structures.
The new method is highly effective and cheap.
