Abstract
Geological disposal of high-level radioactive waste is a worldwide problem. Currently, China is at a critical stage of site selection for an underground laboratory that will be used for field tests of geological disposal. A large amount of multidisciplinary research data has been acquired in the previous site selection processes. Therefore, an integrated geo-information database, called the geo-information database for a pre-selected area (PAGD), and a data management system were specifically designed to facilitate the management of these data. First, an integrated geo-information model was designed to manage the multidisciplinary data. Second, a robust metadata manager was developed for metadata management. Finally, a data management system with B/S and C/S hybrid architecture was developed and realized based on the integrated geo-information database. As a result, a few hundred GB of data from numerous different disciplines were stored and managed successfully.
