Kurzbeschreibung (Abstract)
Tunnel boring machines passing through cohesive soils sometimes experience significant clogging, leading to delays and increased costs. The paper describes a test to assess the likelihood of adhesion problems occurring, simulating the situation where a clay sticks to the cutting wheel of the machine. The results of tests using kaolin clay suggest that the adhesion changes with the compression force. Further studies are being undertaken to elucidate the factors which influence this, including clay mineralogy and roughness of the face of the cutting wheel. It is hoped that the work will lead to an industrial standard method of assessing adhesion which can be used in site investigation and on site.
