Climate change can lead to unpredictable slope collapse, which causes human casualties. Therefore, Korea has devoted significant effort the management of disasters. The Ministry Interior and Safety Korea, oversees safety nation’s people, allocated a four-year budget $557 million investigate, assess, maintain steep sites. However, there have been fatalities caused by site evaluations based on in...

Railway lines typically use traditional sloping embankments as the principal means of track support. However, Geosynthetically Reinforced Soil (GRS) systems have gained popularity alternatives to conventional embankments, particularly for high-speed in Japan. This system requires less ground stabilization/improvement and land take than due its smaller base area. research investigates immediate ...

The in-situ release of fine particles in a porous medium resulting from changes in the colloidal character of fines induced by changes in the electrolytic condition of the permeating fluid and its effects on processes related to enhanced oil recovery (EOR) are examined. Experimental results show that high pH and low salinity cause fines to be released which, in turn, causes a drastic decline in...

EPS geofoam has been used for about 40 years in many geotechnical applications in many countries around the world. EPS geofoam possesses properties which are often advantageous in geotechnical construction. These include: an extremely low density, a high strength-to-weight ratio and very small or virtually zero lateral expansion under compressive loading. It has been used for backfilling retain...

Alpine landscapes have evolved rapidly over the last two centuries. River embankments and urbanization have aff ected most of the large alluvial plains, agriculture has radically changed and its relative landscapes also. Forests are gaining space in most of the Alpine countries and tourism has modifi ed landscapes in several areas, both in alpine forelands and high valleys. In Switzerland, the ...

The overall intent of this research is to develop numerical models of erosion of levees, dams and embankments, validated by physical models. The physical models are performed at 1-g and at high g’s using a geotechnical centrifuge. The erosion is modeled in detail, from beginning to end, that is from the time the levee is overtopped until the levee is breached. Typical quantities measured as a f...

Subsoil support is generally ignored in the design of reinforced piled embankments, resulting a very conservative for settlement control. This philosophy may lead to an unnecessary increase construction costs, especially embankments constructed over subsoil medium and high compressibility (i.e., compression index larger than 0.2). paper presents ground reaction lightly overconsolidated embankme...
