Abstract

Two case histories illustrate the effects that collapse settlement of the fill forming a Reinforced Earth wall can have on the structure. Pre-requisites for collapse settlement are inadequate compaction, compaction at too low a water content, or a combination of these. Collapse settlement occurs subsequently when the water content of the fill is increased by infiltration. The effects of collapse settlement identified in this paper are: (i) a temporary release of friction on the reinforcing strips with the result that the wall facing moves outwards; and (ii) relative settlement between the fill and the wall facing with the result that the reinforcing strips become inclined to the horizontal and their tension increases.

Effects of Collapse Settlement of Fill on Reinforced Earth Walls

Two case histories illustrate the effects that collapse settlement of the fill forming a Reinforced Earth wall can have on the structure. Pre-requisites for collapse settlement are inadequate compaction, compaction at too low a water content, or a combination of these. Collapse settlement occurs subsequently when the water content of the fill is increased by infiltration. The effects of collapse settlement identified in this paper are: (i) a temporary release of friction on the reinforcing strips with the result that the wall facing moves outwards; and (ii) relative settlement between the fill and the wall facing with the result that the reinforcing strips become inclined to the horizontal and their tension increases.
