This paper presents the analytical solutions for the responses of tunnels excavated in rock
masses exhibiting strain-softening behavior. Since previous analyses give little …

The mechanical responses of tunnels reinforced by combined bolt–cable system are
investigated in this paper. An analytical model of the convergence-confinement type is …

A whole-process analytical theory for the coupled deformation of deep circular tunnel
surrounding rock and prestressed yielding anchor bolt (cable) system is derived based on …

In recent years, there is a scenario in urban tunnel constructions to build super-large-span
tunnels for traffic diversion and route optimization purposes. However, the increased size …

This study focused on a new support method, a pretensioned bolt–cable combined support
system, for large-span tunnelling. The Badaling tunnel is a high-speed railway station tunnel …

The shotcrete stiffness varies over time in the hardening period, which complexes the
interaction between support structures and rheological rock. This study presents an …

In this study, based on the construction of a large-span triple-arch tunnel, the authors focus
on the surrounding rock mass deformation characteristic, evolution process of rock mass …

Sprayed concrete lining is a commonly employed support measure in tunnel engineering,
which plays an important role in construction safety. Compressive strength is a key …

Estimating the tunneling‐induced responses of a soil–foundation system is crucial for safety
control in urban underground engineering. In existing analytical research, the soil …

The tunnel water surge seriously threatens the tunneling safety. Based on COMSOL
numerical simulation, the tunneling model is established and the tunneling stress evolution …
