Description
Summary:The aim of the work is the substantiate the development of a GNSS deformation monitoring network at the site of the underground research laboratory, for estimating the safety of underground isolation of radioactive waste in the Nizhne-Kansk massif. The article overviews the international experience of GNSS observations of recent crustal movements in the vicinities of underground research laboratories location (Switzerland, Finland, Sweden). The general information and main results of research works during 2010–2020 in the Nizhne-Kansk geodynamic test area are described. The article presents the prospects for extending the geodetic network in connection with the start of construction of the underground research laboratory. Based on the Delaunay triangulation we have analyzed the triangular finite elements of the existing and planned geodetic network. It is shown that the location of new points will significantly affect the geometry of the network. As a result, the number of near-equilateral triangles in the network will increase, which has a positive effect on increasing the accuracy in determining deformations of the Earth’s surface when processing geodetic measurements.
