FUNDAMENTALS FOR THE DESIGN AND CONSTRUCTION OF TUNNELS LOCATED IN SWELLING ROCK AND THEIR USE DURING CONSTRUCTION OF THE TURNING LOOP OF THE SUBWAY STUTTGART, 1978
The decisive causes for swelling phenomena in connection with tunnel structures, namely the addition of water onto the clay mineral corrensite as well as the transformation of anhydrite into gypsum under addition of water are discussed. A method is described for designing the lining of tunnels in swelling rock. General principles for the dependency of swelling displacements upon the primary stresses, the cross-section shape for the tunnel, and upon the overburden pressure are established. The influence and importance of the quantity of water necessary for the swelling processes are also pointed out.
