Convergence-confinement analysis for tunneling is a standard approach for preliminary
analysis of anticipated wall deformation and support design in squeezing ground. Whether …

This paper presents a simplified procedure to evaluate the failure probability of crossing
tunnels considering the spatial variabilities of rock mass properties. Numerical package …

Surrounding rock control is a big challenge in roadway with high stress in deep
underground engineering. To address this issue, Zhaolou coal mine–a typical kilometer …

When tunneling through deep-buried layered soft strata, asymmetric deformation of
surrounding rock and asymmetric mechanical behavior of supporting structures are often …

Weak rock mass behavior is an important and challenging consideration during construction
and utilization of a tunnel. Tunnel surrounding ground deformation in weak rocks causes to …

To investigate the interaction of the bolt-reinforced rock and the surface support, an
analytical model of the convergence-confinement type is proposed, considering the …

In recent years, with the rapid increase of urban subway lines, crossing engineering has
become another complex problem of modern tunnel construction techniques, and especially …

In the majority of modern rock tunnels the deformation and hence the stability of the tunnel is
controlled by a combination of reinforcement and support systems. The reinforcement …
