Due to the combination of strong earthquakes and heavy rains, a large number of embankments and existing slopes recently collapsed so that the stability and eventual reinforcement of such earth structures are becoming a major concern. On the other hand, in particular for existing slopes, reinforcement usually become costly due to poor working conditions on inclined environments or troublesome due to limited space available for storage or construction. Therefore a new system of slope reinforcement has been developed with emphasis on the ease of construction and cost-effectiveness. The system consists in combining light weight geocells that provide high workability and soil nails that ensure high stability against earthquakes and heavy rains. In this paper are presented a tentative design approach for this new system along with related experimental results including full scale construction tests, as well as examples of actual constructions.
