The most frequently used empirical formulas used to describe the short-term ground surface settlement induced by shield have been presented. Furthermore, a brief description of the numerical model for the simulation of mechanized tunnelling able to predict short-term settlement, i.e. during tunnelling and shortly after it, and as well subsidence of the ground surface due to consolidation process. A significant increase of surface settlement related to the dissipation of excess pore water pressure was confirmed.
