Seismic Stability of Soil Nail Walls


E-1-Background
Vucetic et al (1997) analyzed the stability of soil nail excavation that were shaken by the
1989 Loma Prieta Earthquake. In brief, the performance of nine different grouted soilnailed
excavations in the San Francisco Bay area during the October 17, 1989 Loma
Prieta earthquake was analyzed on the basis of post-earthquake visual inspections,
subsequent stability analyses and dynamic centrifuge model tests. None of the
excavati ....etc

Reinforced soil composite materials, which is formed on the friction of the soil Association and stress resistant elements in the form of sheets, ribbons, nets or mats made of metal, synthetic fabrics or plastics, fibre-reinforced, and located in the mass of the Earth in such a way as to reduce or suppress the deforming strains that develop night by gravity and boundary forces. It is well known that the majority of granwar soil are strong in compression and shear and weak in tension. The performance of such soils can be improved by the introduc ....etc

Abstract

The tensile behaviour of soil plays a significantly important role in various engineering applications. Compacted soils used in geotechnical constructions such as dams and clayey liners in waste containment facilities can suffer from cracking due to tensile failure. In order to increase soil tensile strength, discrete fibre reinforcement technique was proposed. An innovative tensile apparatus was developed to determine the tensile strength characteristics of fibre reinforced soil. The effects of fibre content, dry density and water co ....etc

ABSTRACT:
A new technique for reinforcing rubble stone masonry walls (double and triple-leaf walls), when it is required to keep the fair-face masonry. The reinforcement technique consists of a continuous mesh made of tiny steel cords embedded perfectly in the mortar joints after a first repointing, and anchored to the wall by means of galvanized steel eyebolts driven into the facing. A second repointing covers the cords and the heads of the eyebolts completely. T ....etc
