Eulerian analysis of tunnel excavation with an EPB shield
2018Commonly, Finite Element (FE) analyses of mechanised tunnel excavation are performed using a step-by-step approach, in which a slice of soil elements is removed at each analysis step, representing the soil excavated during the advance phase of the TBM, and a fixed face support pressure is applied at the tunnel face. The complex interactions between the

Soil pressures at the cutting wheel and the pressure bulkhead of an EPB-shield
2014Soil pressureswere measured on both sides of the cutterwheel of an EPB-shield during tunnelling in saturated sand, using foam for soil conditioning. The measured pressures are compared with the pressures at the pressure bulkhead. The pressures are not purely hydrostatic but the results are also influenced by the yield strength of the foam mixture and ...

Evaluation of the clogging potential in mechanical tunnel driving with EPB-shields
2011During mechanical tunnel driving in fine-grained soil or soft rock the excavated material often sticks to the cutting tools or conveying system which may cause great difficulties in the construction process: High energy demand, blocking or breakdown of excavation tools, clogging of screw or band conveyors, problems in stability during the re-use caused
