In case that it is necessary to build a lateral opening in the segmented lining, the opening is formed by breaking out the segments after the TBM excavation is completed or even during the excavation when supply and mucking transport through the tunnel is still active. Most frequent reasons...

  Surface Stabilization and Settlement Mitigation of EPBM Excavations for Prague Metro

  Abstract: In November 2012 two EPBMs completed 4.8 km excavations of twin tunnels for Metro V.A. in Prague. Roadway instability observed during the EPBMs shallow excavations triggered geophysical and drilling exploration works of the roadway subsoil, and intensive monitoring of ground and sewers. The exploration results indicated that the fill under the roadway and the tramway contained voids and had to...
