Effect of the seepage flow on the face stability of a shield tunnel
Tunnelling and Underground Space Technology, 2021To assess the face stability of a shield tunnel excavated in saturated soils under steady seepage flow condition, both numerical simulation and theoretical analysis are carried out.

Seepage Meters in Seepage and Recharge Studies
Journal of the Irrigation and Drainage Division, 1963A falling-head theory and field procedures are presented for measuring seepage and hydraulic conductivity of bottom materials in canals or ponds with seepage meters. Manometer techniques are used for measuring falling head. The method is applicable to uniform bottoms and to material that is underlain by much more, or much less, permeable soil.

Effect of Downward Seepage on Turbulence and Morphology in Mobile Boundary Sinuous Channel
The Physics of Fluids, 2022The porous boundary of alluvial channels allows water to interact with the surrounding groundwater. With the reduction in groundwater level, the transfer of water from the main channel to the groundwater is significant and referred to as downward seepage.

Influence of seepage and tunnel face opening on face support pressure of EPB shield
Computers and geotechnics, 2021The hydraulic head on the tunnel face is smaller than that in the far-field ground when the earth pressure balance shield excavates in a saturated stratum. The seepage force could thus drag the soil to the tunnel face.

Cotransport of heavy metals and SiO2 particles at different temperatures by seepage
, 2020The cotransport of heavy metals (HMs; i.e., Pb2+ and Cd2+) and SiO2 suspended particles (SPs) in a porous medium (quartz sand) at different temperatures was investigated by one-dimensional laboratory column experiments.

A fluid-solid coupled modeling on water seepage through gasketed joint of segmented tunnels
, 2021The water leakage at segment joints of underwater shield tunnels has always been the major concern and trouble to be dealt with in tunneling practices, not only for its threat to the durability and safe operation of tunnels but also for its difficulty to

Grouting effect on rock fracture using shear and seepage assessment
, 2020Evaluation of grouting prior to construction application is necessary. For preparing standard grouting samples, a grouting device was developed. Shear tests and confined seepage tests were conducted on single-fracture chlorite schist with and without ...
