Circumferential yielding lining is able to tolerate controlled displacements without failure,
which has been proven to be an effective solution to large deformation problem in …

According to the convergence confinement theory, it is an effective measure to control the
large deformation of high ground stress in fractured soft rock tunnels by using yielding …

Abstract The Convergence Confinement Method (CCM) is a solution typically employed for
the preliminary evaluation of tunnel convergence and support suitability. The CCM …

Filling material is present around the segment lining when a shielded Tunnel Boring
Machine is used to excavate a tunnel. The two-component grout is becoming lately one of …

The limited efficiency of current supports has led to serious support system problems in
loess tunnel construction, which are mainly noted in arch distortion, shotcrete cracking …

The time-dependent ground response of tunnels in squeezing ground requires a thorough
understanding of the creep mechanism. Several studies conducted assume that this ground …

The convergence–confinement method (CCM), a widely used tunnel design method, is an
analysis approach that can intuitively reflect the interaction between the surroundings and …

For rectangular pipe-jacking construction, the primary priorities of smooth construction
include minimizing the ground response and designating the appropriate jacking force to …

In squeezing ground tunnel construction, yielding elements must absorb the large tunnel
deformation without damaging the tunnel lining. Various designs for these highly …

There is a development trend from qualitative towards quantitative analysis for tunnel
stability. The widely accepted convergence-confinement method (CCM) provides a …
