ABSTRACT
The detailed knowledge of geological, tectonic, hydrogeological and geotechnical features of the host rock is required for the design and safety/performance assessment of a radioactive waste repository. The Hungarian National Radioactive Waste Repository (NRWR) at Bátaapáti is excavated in a highly tectonised granitic formation. Since shotcrete layers are regularly used for supporting, subsequent observation and data acquisition is limited. Accordingly the in-situ documentation must be acquired directly at each excavation front. Before the last construction phase (2014–2015) a new complex system, the Advanced Survey software was developed for the geological, tectonic and hydrogeological documentation, as well as for the geotechnical characterisation at the face (performed with stereoscopic JointMetriX3D/ShapeMetriX3D system, JMX/SMX). Based on the concept of the Advanced Survey software, a spatial database was developed, that would supplement the Advanced Survey software with the analysis of data, analysis of maps, attribute-based and spatial queries. Tunnel advance models and their fracture sets. The data from each excavation drift, fractures sets, boreholes, position and values of rock mechanic laboratory measurements can be exported into ArcGIS. Currently there are three major softwares to access the database: ArcGIS in ArcMap to scan, analyse and query data in 2D, map view; ArcScene for 3D-processing and QGIS (compatible with PostGIS data) to edit and upload data tables to database.
