A New International Database on Case Histories of Monitored Construction of Tunnels and Deep Excavations

The prototype of a new database for case histories of monitored construction of tunnels and deep excavations is presented in this paper. The basic requirements for this database have been established by the members of the Technical Committee TC28 of the International Society for Soil Mechanics and Geotechnical Engineering. It is based on the Content Management System (CMS) Typo3. The resulting structure is flexible, the data being mirrored on sites managed by each participant providing data. It uses a web interface where the user can navigate and access to the data via an indexed search engine. Some very basic and brief standard forms describe the type of work, the geotechnical context and the data available. The monitoring data are organized according to formats chosen by each of the participants. Guidelines and minimal rules have also been proposed in order to ensure that the data can be actually used. Nevertheless, the rules concerning availability/accessibility of the data outside the TC28 partners involved in the creation of the database still need to be discusse
