The safety assessment of tunnel stability is critical to tunnel construction and requires
accurate analysis to obtain a reliable prediction. Strength anisotropy is an important aspect …

In general, the undrained strength anisotropy of clays is found in nature. Its effect on a
stability problem during undrained loading should be considered in order to get a more …

This paper presents a limit equilibrium model for the shield face stability with special
emphasis on the effects of ground heterogeneity and seepage flow. The model considers a …

Based on laboratory and field tests for a cross-river highway shield tunnel in China, the
causes of ground collapse by shield tunnelling in a water-rich fine sand stratum were …

Fluid, particle, and structure interactions are widely encountered in the engineering field.
This study presents a multi-phase coupled method based on computational fluid dynamics …

A novel drainage method using pressure valves to regulate the water pressure acting on the
support system of transport tunnels is proposed in order to reduce water inflow and protect …

This research study aims to determine the stability of a rectangular tunnel excavated in rock
masses obeying Hoek–Brown yield criteria under steady-state groundwater flow using lower …

When tunnels are constructed in coastal cities, they will inevitably undercross a river.
Exploring the influence of rivers on tunnelling-induced deformation in costal soft soil is of …

Seepage is ubiquitous during tunneling in areas with high groundwater tables. The ground
settlement trough on a single tunnel is well described by Peck's formula, but it cannot reflect …

The seepage force can cause failure of the underground excavations and openings that are
lying below the groundwater table (GWT). The present research work aims to estimate the …
