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

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

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

SOFT DRINK BOTTLING PLANT:
Six years after Coca-Cola s bottling plant shut down in India s southern state of Kerala, the company continues to face allegations claiming it caused the depletion of groundwater and polluted the water resources.
Before, the food we cooked used to stay for 7 days. But after this plant came, the water became so bad that the food would spoil in a few hours, says Tangammai, a farm labourer in Kerala s village of Plachimada where the plant operated.
Crops were also affected, says local ....etc

When the company was in the red in 1995 for the first time, BSO restructured the entire board and sent in a team headed by Weston. Soon after he stepped in several changes were made in the management. Indians, who held key positions in top management, were replaced with expatriate Weston taking over as managing director. Mike Middleton was appointed as deputy managing director and R. Senonner headed the marketing division. They made several key changes, including a complete overhaul of the company's operat ....etc
