This paper discusses geotechnical risks associated with founding piles in the Riccarton Gravel. All piles founded within gravels have potential to exhibit similar challenges and parallels can be drawn.
Introduction. The permeability coefficient (k) for soils is the most notable factor in groundwater seepage calculations and analysis. Determination of a reliable permeability coeffi-cient is obligate to reliably calculate, model and evaluate seepage in porous medium.
Some case histories of densification of loose sandy soils using compaction piles are analyzed. The sandy soils were improved to support heavily loaded structures using shallow foundations.

Generally, coarser the soil grains, larger the voids and larger the permeability. Therefore, gravels are more permeable than silts. Hydraulic conductivity is another term used for permeability, often in environmental engineering literature. Flow of water through soils is called seepage.
The behavior of interfaces between coarse-grained soil and gravel-clay introduced by earthquake plays an important role in analyzing the stability of the impermeable structure in rock filling dams. …
1 ημέρα πριν · Practical ApplicationsThe stabilization of noncohesive soils such as marine calcareous sands with lime has been a subject of interest among geotechnical engineers in recent decades. ... the mechanical behavior of calcareous sand specimens stabilized with 4%, 6%, and 8% of hydrated lime and zeolite-to-lime replacement proportions of 0%, 15%, 30% ...
