This study developed a new model, a 3D coupled computational fluid dynamics (CFD)-
discrete element method (DEM) model, by coupling two software programs, ABAQUS and …

The study of waterproof-resistant slab minimum safety thickness for water inrush geohazards
is of great significance during the design and construction phase of tunnel engineering …

Karst caves are often encountered during karst tunnel excavation, and the shape of the karst
cave has an impact on the stability of the tunnel surrounding rock. This paper focused on the …

A semianalytical solution to determine the minimum safety thickness of the rock resisting
water inrush from filling-type karst caves was investigated. Mechanical analyses of the filling …

To study the mechanism and evolution process of water inrush geohazards under the
complex geological environment of the karst cave-fractured zone, a large-scale physical …

Abstract Taking Qiyueshan Tunnel as the engineering background, the three-dimensional
model test system of tunnel water inrush and mud gushing was independently developed to …

Water inrush due to rock mass progressive failure in karst tunnels is one of the disasters in
tunnel construction. The practical measures to ensure the safety of tunnel construction are to …

The existence of karst compromises the safety of underground engineering, especially
during tunnel excavations. Karst conduits are uncovered through tunnel excavations, which …

Instability of filling media in large-scale filled-type karst caves often induce mud inrush in
tunnel construction. An innovative method is proposed for the integral sliding stability …

A simplified computational model used for the stability analysis of the fillings is proposed
based on the simplified Bishop method. In this model, sliding soil, circular slip surface …
