Impact of the expected climate change on the stability of underground cavities in France
Impact du changement climatique attendu sur la stabilité des activités souterraines naturelles en France
Abstract
The different prospective scenarios studied worldwide predict a climate change, with first effects which should be seen before the end of the 21st century. The question is knowing the predictable impact of this climate change on the stability of about a hundred thousand natural and artificial underground cavities which undermine France, notably in karstic regions (limestone, chalk, gypsum). An attempt will be made to describe the different parameters influenced by the climate change and likely to interfere with the stability of underground cavities. The instrumentations set up in situ in artificial cavities as well as the first results obtained and their application to natural cavities, are then presented
