Analysis of an Underground Opening in Jointed Rock
… of the study was to analyze the behavior of an underground rock chamber (Dupont Circle Station) excavated in jointed rock. The chamber was excavated in five stages and was driven in foliated metamorphic rock whose main features consisted of joints, shears and shear zones. The study included the …

The effects of the pressure arch upon multiple seam mining
… extent and magnitude of the stresses above an underground opening. The finite element approach was utilized to determine the extent and magnitude of stresses for various widths of mine opening, depths of cover and overburden material. This information can then be used as an approximation of the …

A Boundary Element Method for Thermo-poroelasticity with Applications in Rock Mechanics
… the stresses and pore pressure fields around an underground opening. This is due to the fact that thermal loading induces a volumetric deformation because of thermal expansion/contraction of both the pore fluid and the rock solid. Volumetric expansion can result in significant pressurization of …

MPM Modeling of Internal Collapse Under Levees Caused by Underground Openings
… safety. This study investigates the mechanics of underground trapdoor collapse in frictional and cohesive soils, which is relevant to the behavior of water-retaining structures like levees, e.g., subjected to pipe leakage. The Material Point Method (MPM), an advanced numerical tool capable of …
