WebApr 1, 2024 · Due to the sudden reduction of void geometry from base soil to filter material, the eroded fines from upstream soil in the dam would ideally clog and accumulate at the shell-filter interface; then part of the fines might continue to migrate in the filter or even effuse into the neighboring soil matrix. WebMar 20, 2024 · Seepage has a significant impact on the failure mechanism and support pressure. The permeability of tunnel working face is the key factor leading to the difference in support pressure under different hydraulic conditions [ 19 ].
WebErosion Control Stone and concrete revetments are often used on waterway slopes to resist soil erosion. These armored systems, when placed directly on the soil, have not suffi-ciently prevented erosion. Fluctuating water levels cause seepage in and out of embankment slopes resulting in the displacement of fine soil particles. WebJan 13, 2024 · However, clogging can reduce permeability, leading to an increase in excess pore pressure and strength degradation. Finally, the arch can be destroyed by fluid flow, causing permeability reduction and abrupt erosion.
