Abstract
The stabilized earth or reinforced soil structure comprises a fill, a facing placed along a front face of the structure, main reinforcements disconnected from the facing and extending in a reinforced zone of the fill situated behind the front face, and secondary elements connected to the facing and extending in a zone of the fill which exhibits, with the reinforced zone, a common part where loads are transmitted between the main reinforcements and the secondary elements by the material of the fill.
Claims17
A stabilized earth structure comprising:
- a fill with a front face;
- a facing along said front face;
- main stabilizing bands disconnected from the facing and extending through a first stabilized zone of the fill for stabilizing said first zone of said fill, said bands situated separate from, spaced from and behind said facing;
- secondary stabilizing members connected to the facing and extending in a second stabilized zone of the fill stabilized by friction between the stabilizing members and said second zone of said fill, said second zone extending between the front face and partially into said first zone which has, with said first stabilized zone, a common part where loads are transmitted between the main stabilizing bands and the secondary members by only the material of the fill.
A method for building a stabilized earth structure, comprising the steps of:
- positioning a facing along a front face of the structure delimiting a volume to be filled,
- placing main mechanically stabilizing bands in a first zone of said volume, wherein the main stabilizing bands are not permanently connected to the facing and extend through the first zone,
- placing secondary mechanically stabilizing members connected to the facing in a second zone of said volume, said first and second zones having a part in common, and
- introducing fill material into said volume and compacting the fill material, whereby once the fill material has been introduced and compacted, loads are transmitted between the main stabilizing bands and the secondary members by only the fill material situated in said common part and each zone is mechanically stabilized by the stabilizing members or bands therein.
