Abstract

The on-site treatment of sewage is common in all rural and regional areas of the world. Due to the public health and environmental risks that these treatment systems pose, the need for adopting performance based management strategies is gaining increasing recognition. This demands the establishment of performance objectives for on-site sewage treatment and disposal which are based on stringent scientific analysis. A research project was undertaken to identify and investigate the role of influential site and soil characteristics in the ....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

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 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

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
