About this document

TBM Tunnelling: Convergence-Confinement Analysis by Nguyễn Hòa is a document available to read on EtoBox.

When a tunnel is excavated below the groundwater table, groundwater may flow into the tunnel and, consequently, seepage forces may develop in the ground seriously affecting the behavior of the tunnel. Ground response to tunnelling can be understood theoretically by the convergence-confinement method. This method is based on the principle for which a tunnel is stabilized by controlling its displacements after installation of a support near the tunnel face. The convergence-confinement method is based on
