Deformation calculation of the reinforced tunnel is always the key and difficult problem in
tunnel support design. To achieve simple and rapid tunnel performance evaluation, this …

Tunnels embedded in soft rock masses experience time-dependent behaviour, and
designing an appropriate supporting system is a challenging task. This condition can be …

Different calculation methods and modeling strategies are commonly used in engineering
practice to predict the internal forces in segmental tunnel linings. Accordingly, the calculation …

According to the excavation methods of tunneling, a damaged zone may be developed in
the rock mass around the tunnel, the mechanical properties of which can be significantly …

In this paper, an analytical-numerical method is presented to study the long-term behavior of
pressurized tunnels. In this regard, the pressurized tunnel construction is simplified into …

A new theoretical method is proposed to simulate the fiberglass dowels performance in the
confinement of the tunnel face in weak rock masses. In this method, to find the stress …

Long-term tunnel displacement prediction is of great engineering significance to tunnel
maintenance and hazard warning. To that end, this paper provides a novel combination idea …

Abstract Design of pressurized tunnels in rock masses which have a time-dependent
behavior is a challenging task. On the one hand, time-dependent behavior not only imposes …

If an underground opening is excavated using the drill and blast method, an excavation
damaged zone (EDZ) will appear around the opening in which it's mechanical and creep …

The surrounding rock is in the initial stress state before the tunnel excavation, and it
undergoes the stress redistribution to reach the secondary stress state after the tunnel …
