MEASUREMENT OF GROUND MOVEMENTS DURING A BENTONITE TUNNELLING EXPERIMENT

The report describes the ground movement and pore-pressure measurements carried out during the construction of an experimental tunnel at new cross, London using the bentonite tunnelling process. The measurements confirmed the ability of this process to limit ground settlements in reasonably dense cohesionless soils to values similar to those produced by conventional tunnelling methods in London clay. /Author/TRRL/
