Degree of Saturation and Liquefaction Resistances .

Traduire cette page

Sand compaction pile (SCP) is a ground improvement technique extensively used to ameliorate liquefaction resistance of loose sand deposits. This paper discusses results of laboratory tests on high-quality undisturbed samples obtained by the in situ freezing method at six sites where foundation soils had been improved with SCP.

Compaction of Soil – Process, Necessity and Theory of ...

Compaction of soil is an important process, as it helps it of achieve certain physical properties necessary for its proper behaviour under loading: for example proper compaction of an earthen dam or a highway Embankment reduces the chances of its settlement, increases the shear strength of the soil due to its increased density and reduces the permeability of the soil.

Principle of Vibro Compaction. The method of soil improvement whereby granular soils are compacted using depth vibrators is known as Vibro Compaction or Vibroflotation. Naturally deposited soils as well as artificially reclaimed sands can be compacted to great depths. The current depth record lies at 70 meters for reclaimed sands and at 53 meters for naturally deposited sands. The intensity of ...

Applicable Soils & Depth of Improvement. The Vibro Compaction technique is best suited for loose sand to coarse-grained soil with a silt/clay content of less than 10% (less efficient with a fines content between 10% and 15%). The technique applies to depths up to 45m (or more, depending on the crane capacity). The Vibro-Replacement (stone columns) is most suitable for sand .
