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 …

Surface settlement (SS) resulting from tunnel excavation operations is a critical concern in
tunnel engineering due to its potential impact on adjacent structures. This review …

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 …

The horizontally layered or even inclined strata are often encountered in practical shield
tunneling. The influence of inclined strata on face stability of shield tunnels is not fully …

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 …

Tunnels are classified as civil engineering infrastructure which serves various functions that
are primarily associated with transportation of vehicles and liquids. Their design and …

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 …

Based on the three-dimensional hydraulic head distribution model and the upper bound
theorem of the limit analysis, a new model was established to calculate the limit support …

This paper aims at proposing a new failure mechanism to deal with the face stability of deep
tunnels in sandy layer. Numerical simulations were conducted to analyze the influence of …

In order to investigate the influence of face instability for tunnels with different burial depths
in sandy cobble strata on earth pressure and the instability region, geomechanical model …
