     it is a well known practice – most of the claims on tunnelling are due to unexpected geological conditions whereas in many cases where tbm have been used it should be clear that ground properties as described in the geotechnical baseline report (gbr) are very likely to be changed during the excavation by the tbm. so a contractual line has to be drawn between the term unexpected ground conditions and expected permanent changes of muck properties caused by the tbm. from a contractual point of view it is very important for both sides – owner and contractor – to have the best assessment on the ground properties in the gbr which have been gained from traditionally quasi-static exploration tests in the laboratory. however, the excavation and mixing of the ground in the working chamber of a tbm is far away from being quasi-static but are highly dynamic to chaotic why traditional soil mechanics have to be judged critical in this case.
