... there is a mapped fault running through this location. It is a requirement of the rail authority, Mass Transit Railway, MTR, that any tunnel excavation induced deformation and vibration within the existing metro is monitored and controlled to pre-determined levels. If these allowable limits are exceeded, tunnelling...

... of a TBM tunnel are both illustrated in flowchart. Also, a simple example of a double shield TBM tunnel excavation is implemented based on BLKLAB and the corresponding removable blocks are analyzed. Moreover, a representative excavation step is picked out to illustrate the removable blocks around the TBM...
