Why do Slurry Shield TBMs have difficulty when tunneling ...

Slurry Shield TBMs are widely used for non-cohesive soils ranging from fine-grained sand to coarse-grained gravel. It is less suitable when operating in clay because: (i) Most slurry separation plant could not separate clay from slurry. As such, the cost of frequent replacement of bentonite slurry is substantially increased.
