The use of yielding supports has proven to be a highly effective measure for tunneling in
squeezing grounds because of their agreement with the law of mechanical movement of …

The complicated tunnelling conditions and variable engineering demands have made
numerous challenges of mesh-reinforced lining structures. Thereafter, the steel fiber …

With the rapid increase in the construction of loess tunnels, more and more problems are
encountered during the construction process, especially regarding the issue of collapse in …

Rockburst seriously threatened construction safety of deep traffic tunnel in high geostress
condition. In recent years, a large number of deep traffic tunnels have been constructed in …

Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it
reduces dead loads on the structure and foundation, contributes to energy conservation, and …

Tunnelling in ground fissure areas is prone to collapse even with reasonable reinforcement.
Based on the collapse of a tunnel in Xi'an Metro Line 3 near a ground fissure, potential …

In face of the complicated and changing geological conditions, safety issue is always a
primary concern during the construction phase of tunnel in the mountainous regions of …

In this study, a new approach based on DEM was developed to simulate the damage of
water-rich rock after freeze–thaw cycles. In this way, water-rich rock samples at low …

As a typical discontinuous medium, the boulder-cobble mixed strata (BCMS) are often faced
with the problems of easy collapse and difficult to effectively support in the construction of …

Karst landforms were widely distributed all over the world, and they were mainly distributed
in the Southwest and Southeast regions in China. However, tunnel construction in giant …
