Behavior of Prototype Steep Slope Embankment Having Soil-Walls Reinforced by Continuous Fibers

Failure of Reinforced Earth as Attacked by Typhoon No. 23 in 2004

“…The gap between the upper and lower shear boxes was maintained at a constant value of 0.5 mm during shear, noting the mean diameter of about 0.1 mm for the soil tested. The soil density was 1.7-1.8 g W cm 3 being very close to the in-situ density.…”

“…Moreover, when considering the need for reducing the construction cost, local government is often obliged to use local soils with low permeability and low friction angle in constructing Reinforced Earth wall. Despite that the stability of reinforced walls is usually threatened by rainfalls (e.g., see Kutara et al, 1991), a proper drainage system around the wall tends to be optional, not obligatory, in the light of the current format of the design and construction manual for this type of wall. Geotechnical engineers have therefore been concerned with the shortterm stability of Reinforced Earth in the event of annual typhoon attacks as they are constructed in a mountainous region.…”
