SOME NORWEGIAN STUDIES AND EXPERIENCES WITH SWELLING MATERIALS IN ROCK GOUGES

In Norway construction works in rock have increased considerably in the last fifteen years. Frequently fissures and crushing zones filled with clay or clay-like materials are found. These materials may cause difficulties during and after construction, as they in some cases swell, in other cases are exposed to erosion. It is demonstrated that the occurance of failures in tunnels in many cases can be correlated with the presence of montomorillonite. Some typical case records are given and some laboratory experiments concerning swelling and swelling pressures are described. Conclusively the importance of recognizing dangerous gouge and taking precautionary measures on the site is stated.
