Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquake around the world. Especially, its devastating effects sprang to the attention of geotechnical engineers in a three-month period in 1964 when the Niigata earthquake in Japan followed the Good Friday earthquake in Alaska. Evaluation of liquefaction resistance of soils is an important step in many geotechnical investigations in earthquake-liable region. The most common procedure around the world for evaluating liquefaction resistance ....etc

Liquefaction
Liquefaction is a physical process that takes place during some earthquakes that may lead to ground failure. As a consequence of liquefaction, soft, young, water-saturated, well sorted, fine grain sands and silts behave as viscous fluids rather than solids.
Liquefaction takes place when seismic shear waves pass through a saturated granular soil layer, distort its granular structure, and cause some of its pore spaces to collapse.
The collapse of the granular structure increases p ....etc

Soil liquefaction describes a phenomenon in which a saturated or partially saturated soil loses substantially resistance and rigidity in response to applied stress, usually seismic agitation or other sudden change in the stress condition, causing it to behave like a liquid. Saturated, loose (low density or non-compacted), sandy. This is because loose sand tends to compress when a load is applied; Dense sands by contrast tend to expand in volume or 'dilate'. If the soil is saturated by water, a condition that often exists when the soil is below ....etc

SEMINAR REPORT ON EVALUATION OF FLOW LIQUEFACTION AND LIQUEFIED SHEAR STRENGTH USING CONE PENETRATION TEST


ABSTRACT

Flow liquefaction is a major design issue for large soil structures such as mine tailings impoundments and earth dams. If a soil is strain softening in undrained shear and, hence, susceptible to flow liquefaction, an estimate of the resulting liquefied shear strength is required for stability analyses. Many procedures have been published for estimating the residual or liquefie ....etc

shearing strength of soil seminar

Shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. The shear resistance of soil is a result of friction and interlocking of particles, and possibly cementation or bonding at particle contacts. Due to interlocking, particulate material may expand or contract in volume as it is subject to shear strains. If soil expands its volume, the density of particles will decrease and the strength will decrease; in this case, the peak strength would be foll ....etc
