Transient one-dimensional wave processes in a layered medium

Waveguide properties of a block geomedium are studied by using a regular structure composed of elastic layers with elastic inertialess interlayers. The analytical solution of the problem is derived. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 2, pp. 41–54, March–April, 2007.     

Modeling the elastic wave propagation in a block medium under the impulse loading

The wave propagation analysis revealed that the low-frequency pendulum wave propagating in a 2D block medium with periodic structure due to the action of local impulse has a two-wave structure. The shape of such wave depends on its propagation direction. Modeling the blast-induced seismic wave propagation in a two-layer block rock mass with the weak upper layer and stiff lower layer showed that the far distant point from the wave excitation source is first reached by the small amplitude pendulum wave running in the stiffer lower layer and then by the delayed maximum-amplitude wave propagating in the upper layer.     

Attenuation law of explosive stress wave in damaged rock mass

The attenuation regularity of explosion stress waves in damaged rocks is discussed according to physical and geometric attenuation of waves in this paper. The relation between numerical decrement and damaged parameter is given and the results have an important significance to design and control blasting effect accurately in a concrete rock.
