Support is one of the most important aspects that contribute to long-term stability and tunnel
safety. Lining cracking and even failure often occur during tunneling construction, especially …

Installing flexible layer is one kind of supporting techniques to deal with the large
deformation in tunnels excavated in viscoelastic rocks. The role of flexible layer is to absorb …

For long-distance water conveyance shield tunnels in operation, the high internal water
pressure may cause excessive deformation of composite linings, affecting their structural …

The time-dependency in tunneling is mainly due to the rheological properties of the rock and
tunnel construction processes. Rock rheology results in tunnel convergence and pressures …

The construction of underground tunnels is a time-dependent process. The states of stress
and strain in the ground vary with time due to the construction process. Stress and strain …

The loads on primary support and secondary lining in composite lining tunnel are one of the
key problems in support design. The primary support and secondary lining which as the …

The composite lining load of a deep-buried tunnel is one of the key problems in tunnel
support design. This study establishes four support cases to discuss the loads on primary …

The stability control of surrounding rock is always one of the important problems in tunnel
construction. As a representative of tunnel pre-construction technology, advance grouting …

Slate is a metamorphic rock often contains a dense foliated texture called slaty cleavages or
schistosities. The ease of split along the schistosities weakens the slate and its resistance to …

Theoretical analysis is used to predict the dynamic response of a circular lined tunnel with
an imperfect interface to plane SV-waves. The linear spring model is introduced to depict the …
