Owing to complex and lengthy geological processes, inclined layered soils are frequently
encountered in geological and geotechnical engineering. Tunneling in such strata threatens …

Existing mechanism of simulating soil movement at tunnel face is generally based on the
translational or rotational velocity field, which is, to some extent, different from the real soil …

This paper adopted both the numerical and analytical methods to investigate the excavation
stability against base heave failure. The finite element limit analysis method (OPTUM) was …

To better assess the stability of tunnel faces in cohesion-frictional soils, tunnel face stability
was investigated considering the soil arching effect in this study. An improved 3D rotational …

This paper aims at influence of relative density on deformation and failure characteristics for
a shield tunnel in sandy cobble strata. A series of model tests were performed for tunnels …

Soft ground tunnelling in urban areas is more frequently being performed using the shield
method. Due to its great influence on both ground settlement and construction safety, face …

The face stability of a horseshoe-shaped shield tunnel in undrained clays with a linearly
increasing strength is numerically and analytically investigated in this paper. Based on the …

The tunnel face stability is a key issue to ensure the engineering safety. Combined with
model tests and numerical simulations, this paper focuses on progressive settlement …

This paper focuses on analytical solutions of additional stresses for a curved shield tunnel.
General equations of additional stress caused by construction loadings were deduced by …

This paper aims to study the influence of relative density on the working face stability of
shield tunnel in sandy cobble stratum. A series of geomechanical model tests were …
