This study research investigated the seismic effects on the design of retaining walls. The basic analysis theory of retaining structures under static load is the Coulomb theory, stating that the pressure of a loose body on the lateral surface is determined from the static equilibrium condition of rigid wedge formed in the bed between backsides of the structure and slipping area, considering the wedge as rigid body. Dynamic pressure of the soil was studied in the works of Okabe and Mononobe. Currently, these studies are basic in the preparation of regulatory documents.

On the use of seismic Rayleigh waves in security systems

There are four types of seismic waves: primary waves , secondary waves , wave Rayleigh and Love waves. The first two types are called depth waves, because these waves penetrate into the depths of the earth. Rayleigh waves and Love waves called surface waves. They can to propagate on the surface. Given the characteristics of propagation of these waves can be concluded that even at low energies excitation source, Rayleigh waves can propagate at a much greater distance than depth waves, so it would be advisable to use them in security systems.

Seismic system for monitoring and forecasting local earthquakes in the Dnepropetrovsk region

Summarizes the results of preliminary studies to ascertain the nature of earthquakes and seismic safety in the provision of technologically-risk areas Krivoy Rog iron ore and coal basins Pavlograd. The possibilities of highly sensitive seismic stations UK15, established in Dnepropetrovsk (n. Mirnij), check local and remote Kryvyi Rih and Pavlogradskij earthquakes.

Solving the inverse problem of seismic prospecting using the energy approach to the analysis of wave fields

In the paper the implementation of energy wave field analysis approach for developed informational model of the geological medium is considered. The solutions of seismic inverse problem are presented, which involves geophysical parameters obtaining of geological medium with the use of field seismic data. In order to obtain geological and geophysical environmental parameters the number of wave field transformations are being carried out, conventionally divided into primary and final part (interpretation).
