Abstract
During mechanical tunnel driving in fine grained soil or rock the excavated material often sticks to the cutting tools or conveying system, which may cause great difficulties in its excavation and transport. In the InProTunnel project this problem is faced on different scales particularly for the method of Earth Pressure Balanced (EPB) shield tunnelling. Major influences from tunnel boring machine (TBM) operation are identified by project data analyses, clogging propensity is evaluated by a new laboratory test, alternative manipulation techniques are developed based on modifications of the physico-chemical and electroosmotic behaviour of clay minerals and will be tested in an especially designed clogging test system.
