Prieto-Portar 2009 Sheet-pile walls must not only retain the backfill behind the wall, but in addition, they must support many other large surface loads. These loads are of great importance for ports, industrial yards, railroads, highways, etc. The most common of these surface loads are: 1) Uniform surcharges on the deck behind the sheet-pile wall; 2) Point loads behind the wall; 3) Line loads parallel to the sheet-pile wall; and 4) Strip loads parallel to the sheet-pile wall; 1) Uniform Surcharge Loads. A uniform surcharge load q on the deck behind the sheet-pile wall could consist of, for example, stacks of loaded TEUs (twenty-foot equivalent units) containers, or piles of mineral ores, sand or gravel, merchandise, etc. These surface loads q produce vertical pressures at depth that add to the vertical pressure from the backfill itself (...
