The aim of the study is to identify the recent local geodynamic processes on the territory of the Dniester PSPP (Ukraine), which arose as a result of the additional man-caused load during the construction of hydro-technical structures. The research is based on the results of 17 cycles of periodic static GNSS campaigns conducted during 2004-2017. In this work the vectors of horizontal displacement of the reference GNSS network points of Dniester PSPP are determined and their scheme is constructed. On the basis of average vectors of horizontal movement velocities during 2004-2017, the value of the velocities of dilatation - the parameter of Earth surface deformation which characterises the relative area expansion or compression, is calculated. As a result of the analysis of velocity distribution of the dilatation of Dniester PSPP territory, the areas of extreme values of compression and stretching are revealed, which testify to the increased geodynamic activity of the pivot part, as well as the main structures of the construction. and Savchyn Ihor, Vaskovets Serhii.
An approach to risk evaluation against the failure of waste deposit sealing layer is given. It is derived from experience gathered with municipal waste deposit closures. Such deposits were monitored in Ce ntral Bohemia in the territory of the Czech Republic. Geodetic observations on such deposits carried out for five to eleven years provided a chance to obtain and interpret continuous deformation data series. Results can increase functional reliability of their superficial sealing and can be used to optimise the time when closure and recultivation should start. The results concern superficial settlement, its development in time and irregularities that are practically very important. Definition of failure criteria that would allow evaluation of limits in irregular deposit se ttlement is relatively difficult and should become a topic for further investigations and discussions., Zdeněk Kudrna., and Obsahuje bibliografické odkazy
