Abstract soil-cement is a mixture produced by grouting or mixing cement with soils. This
paper reviews and discusses the general classifications of grouting techniques and the …

Pre-support systems are very important for inner-city shallow tunnels in order to minimize
twin tunnel-induced surface deformations. However, previous studies concerning the …

A distributed optical strain-sensing technique is presented as a solution for measuring the
strain distribution along ground support members used in tunnelling and mining works. The …

One of the main factors that affect the tunnel face stability is the free or unsupported span (ie,
the unlined length adjacent to the tunnel face). In this work, a 2D failure mechanism is …

Hard rock formations with layered, anisotropic geological structures are rather common in
Norway. The design of tunnel rock support under such ground conditions has been …

This paper presents an analysis of the influence of the umbrella arch on the settlements
induced by shallow tunneling, based on three-dimensional finite element simulations using …

Methods of approximation that predict the mechanical responses of the tunnel support
systems in conjunction with ground behaviour are invaluable to the tunnel design engineer …

The 11 km long Sabzkuh water conveyance tunnel is under construction using conventional
and tunnel boring machine tunneling techniques in the Zagros Mountains of south west Iran …

In this study, a simple analytical method is presented to investigate the behavior of arch
umbrella supporting system (the forepolling system) in deep tunnels. For this purpose, a …

Tunnelling in urban environments often poses serious concerns regarding potential
detrimental effects induced on the surrounding structures and infrastructures, as in the case …
