The face failure of tunnels has been extensively studied. However, the effect of particle
shape on the failure process still remains unclear. In this paper, the progressive face failure …

The macroscopic phenomena and microscopic origin of penetrative migration and retention
of fine particles in porous skeleton under the action of seepage are not yet clear. Migrating …

The flow direction is generally different from the gravity direction in geotechnical structures
or slopes, the effect of which during suffusion remains unclear. This paper presents a …

Suffusion is one of the most common causes of hydraulic geological structure failure. During
the suffusion process, particle shape is a significant factor to affect the micro-structure and …

The mechanical behavior at soil–structure interface (SSI) has a crucial influence on the
safety and stability of geotechnical structures. However, the behavior of SSI under constant …

Slit-type barriers serve as active countermeasures against debris flow. However, the
dynamic interaction between debris flows and slit-type barriers is extremely complicated. To …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

For tunnels built in the saturated silty sand ground, fine particles may be migrated into
tunnels through seams of tunnel segmental joints and then seepage erosion is triggered …

Underground excavation is usually accompanied by complex soil-structure interaction
problems in practical engineering. This paper develops a novel multi-scale approach for …

Soil arching is a common phenomenon in many underground engineering problems. This
paper develops a coupling approach involving the Finite Element Method (FEM) and …
