New generation tunneling shields for soil are capable of exerting a positive pressure on the soil at the face and inducing an initial heaving effect not observed with conventional shields. This is important to control ground movements and creates a more complex situation than heretofore encountered in finite element analysis of this problem. Several soil and tunnel construction models are considered and tested against case history data for their ability to predict observed behavior for an advanced shield. (Author abstract. ) Refs.
