SEMOTI - Development of a self-learning modelling methodology of the geomechanical and geotechnical processes for the planning and excavation phase of an emplacement drift of a deep geological repository

Problem definition

Based on the Repository Site Selection Act (StandAG) Germany is currently searching for a repository site for high-level radioactive waste. Therefore investigations are conducted in deep geological formations (depth > 300m) which are expected to provide the best possible safety. The planning of a deep repository is based on engineering models, whose validity must be permanently verified by measurements of changes in state during the excavation of the underground cavities, the emplacement operation and the closure phase. As part of a self-learning process, the data obtained offers the possibility of recognizing undesirable developments and, if necessary, deriving consequences from them.

Objectives

The overall goal of the research project is to develop a machine learning-based modeling method for high-level-radioactive-waste disposal systems, which enables an optimization process during the planning phase and a calibration process during the excavation phase in the area of geomechanical and geotechnical issues. This method is being developed as an example for the virtual demonstrator “Emplacement drift with backfill and sealing structure in rock salt”.
