Abstract

In the present paper, results of empirical, analytical and numerical methods for determination of face support pressure in mechanized tunneling and measurements of tunneling induced surface settlements and applied face support and grout injection pressures during the construction of Tabriz underground railway line 2 (TUR2) are presented. Face pressure plays an important role in the evolution of tunneling induced-ground movements. Determination of optimum face stability pressure is a major challenge in TBM tunneling.
