Paper Number: ISRM-IS-2000-563
... ABSTRACT: Large scaled model tests were carried out to study the short-term deformation behavior of the arch-shaped tunnel which was constructed by cut-and-cover method without compaction effort for backfill material. Earth pressures acting on the tunnel lining and displacements of the lining...

This paper describes the interaction between the ground and shotcrete tunnel linings for tunnels driven in materials that deform and are displaced as a result of excavation, such as soft ground and weak rock in shallow civil engineering scenarios. The relative stiffness of shotcrete...

.... INTRODUCTION Since the advent of the New Austrian Tunneling method (NATM) due to Rabcewicz and Golser (1973), use of bolting as a lining support has become more and more popular in tunneling projects, encouraged by the real efficiency observed on site. However, it turns out to be rather difficult to account...
