An Integrated Relational Database for Tracking Rock Mass Data During Tunnelling

摘要

There is an immense amount of geological and monitoring data that can be collected during tunnelling.rnThe organization and ready use of this data determines how effectively the data can be utilized in realtimernanalysis and visualization. The ongoing collaborative research project AMADEUS (AdaptivernReal-Time Geological Mapping Analysis of Underground Space) being conducted at Virginia Techrnwhich integrates real-time data collection, analysis, and visualization of geological and monitoringrndata as a tunnel is advanced. A well structured database is a key component to the success ofrntunnelling operations when large amounts of data are acquired. A database for tracking and organizingrntunnelling data has been designed as a part of the AMADEUS research project. This paper providesrndesign details of this database and its implementation to AMADEUS.rnThe database design allows for the integration of the main aspects of the AMADEUS project,rnwhich are as follows: digital imaging and interpretation of tunnel geology, statistical processing ofrnjoint data to build stochastic geological models, development and advancement of computational toolsrnfor rock mass modelling, computer tomography to detect and map stress changes and concentrations,rnvirtual environment (VE) for visualization & interaction with a virtual excavation model. Using therndatabase to integrate all these aspects, allows for quick reliable recording and sharing of location basedrndata.
