GEOLOGY FOR ROCK ENGINEERING PROJECTS
To be confirmed
The short course deals first with a recall of basic data of structural geology, presenting the different processes of genesis and resulting characteristics of the main types of rock masses, with emphasize on fractured masses. Thereby is presented how to define a site investigation really adapted to the
Then, the methods of analysis of site geotechnical conditions of rock masses are described, including rock mass classification. Interest and limitations of these classifications will be highlighted and illustrated, based on the use of structural geology during mapping.
Obtaining sound data via adapted investigation equipment, as well as the process of data validation will then be exposed, from the rock matrix scale to the rock mass of the site. Particular emphasis is put on the influence of groundwater and groundwater circulation over properties of the rock masses,
including how these can be taken into consideration.
The second part of the short course will focus on follow‐up during construction, demonstrating the prime importance of continuous data acquisition during this phase, such as geological/geotechnical mapping of excavation faces. For this purpose, examples will be analysed from real industrial
projects. How original design assumptions and design values can be validated and/or updated will also be presented on the basis of case studies.
The end session will describe the monitoring instruments, and how to select the most suitable devices for the validation or updating of design parameters.
A fruitful exchange with the attendees of the short course is expected at the end of the day.
