Effect of pore-size distribution on the collapse behaviour of anthropogenic sandy soil deposits
E3S Web of Conferences, 2016 In the former open-pit mines of the Lusatian region in Germany, several liquefaction events have occurred during the recent years in the anthropogenic deposits made of very loose sandy soils.

Expansion mechanisms in sulphated rocks and soils
, 2023 Geological formations containing sulphates are commonly associated with the development of severe expansions when they are involved in tunnel excavation. The intensity of the observed expansive behaviour in these materials is greater than in other expansive soils and rocks free of sulphates.

Stress dependent thermal pressurization of a fluid-saturated rock [PDF]
, 2009 Temperature increase in saturated porous materials under undrained conditions leads to thermal pressurization of the pore fluid due to the discrepancy between the thermal expansion coefficients of the pore fluid and of the solid matrix.

Investigation of Lateral Stress Relief on theStability of PHI = 0 DEG Slopes Using Laboratory, Fracture Mechanics, and Finite Element Method Approaches [PDF]
, 2011 Total stress analyses of purely cohesive cut slopes utilize the undrained shear strength for slope stability analyses. These slopes can have an in-situ lateral earth pressure that is greater than the vertical pressure.
