Kulish E. The vibration diagnostic of anchor against landslide construction.

The dissertation is devoted the improvement of method of vibration diagnostics for the anchor against landslide construction.The discrete diagnosis models are developed and investigated for the following con-structions: beam and plate The influence of crack-like damage on native frequencies and forms of oscillations is researched for constructions of various type, as beam and plate. De-pendencies of native frequencies and first three forms of oscillations are received and inves-tigated at the various crack sizes and crack locations. The discrete diagnosis model of an an-chor against landslide construction is developed and researched for definition of depend-ences between parameters of an anchor condition and vibrating characteristics of a retaining wall at the various kind of rod fixation, which is accessible to carrying out of measurements. The discrete diagnosis model of complex construction of an anchor against landslide con-struction is developed. The analysis of anchors oscillations shapes and frequencies is carried out for different operating conditions of against landslide construction, the functional de-pendencies of natural frequencies on fixation and rigidity of rods are defined. The experi-mental researches are carried out for real anchor against landslide constructions. The evalua-tion of parameter of changing rigidity of rod is carried out by using the maximum likely-hood method, the estimations are calculated and investigated. Keywords: anchor against landslide constructions, rod tensioning, vibration diagnos-tics, discrete diagnosis models, native frequencies and forms of oscillations, motion of a re-taining wall.
