Difficult Ground Solutions: A Methodology for Enhanced TBM Performance in Challenging Conditions | Paper Author: Doug Harding

In many rock projects, the occurrence of squeezing ground, high inrushes of water, blocky rock, and other challenges is a real possibility.  Today’s highly adaptable TBMs are capable of tackling these tough conditions using cutting-edge technology coupled with modern ground investigation methods. Difficult Ground Solutions (DGS)—a series of adaptable and customizable features for shielded TBMs—can reduce risk to contractors and owners while providing accurate ground investigation.  This paper covers difficult ground solutions informed by field experiences, the tools it takes to be successful in such conditions, and how they are applied. Example projects will be discussed from the U.S., Turkey, Nepal, and more.
