Experimental study on progressive failure process and permeability characteristics of red sandstone under seepage pressure

Engineering Geology, 2020
Rock masses in underground spaces often experience in-situ stress field and seepage field coupling which gives them complex mechanical behavioural and permeability characteristics. In this study, a High Pressure Triaxial Automated System for Rock (HPTAS)

Effects of seepage-induced erosion on nonlinear hydraulic properties of broken red sandstones

Tunnelling and Underground Space Technology, 2019
Water inrush hazard is a major threat to safe mining and tunnel construction. During the water inrush process, nonlinear properties of rock mass can change gradually due to the erosion of flowing water.

Seepage characteristics of chemical grout flow in porous sandstone with a fracture under different temperature conditions: An NMR based experimental investigation

, 2021
In this study, the low-field nuclear magnetic resonance (NMR) testing technique was adopted to experimentally investigate the seepage processes of chemical grout flow in fractured rock under various temperatures and confining pressures. The variations in

Permeability and seepage

1995
As a result of the hydrological cycle (rainfall, infiltration) it is inevitable that the voids between soil particles will fill with water until they become fully saturated. There then exists a zone of saturation below ground level the upper surface of which is called the water table.

Analytical solutions of non-Darcy seepage of grouted subsea tunnels

Tunnelling and Underground Space Technology, 2020
Fluid flow in porous media is very important in a wide range of hydraulic and geotechnical engineering fields. The theoretical basis of fluid flow in porous media is based on the Darcy’s law.
