Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
A scaled down version of this design, the Small Box Girder Bridge, was also formally adopted by the Army in 1932. This latter design was copied by many countries, including Germany, who called their version the Kastenträger-Gerät (K-Gerät for short). [2] The United States was another country whose army created their own copy, designating it ...
In the early 1970s, a number of box girder bridges collapsed during construction: the Cleddau Bridge in Wales, West Gate Bridge in Australia and the Koblenz Bridge in Germany. That led to serious concerns over the continued use of box girders and extensive studies of their safety, which involved an early use of computer modelling, and was a ...
The design was patented in 1820 by architect Ithiel Town. Originally a means of erecting a substantial bridge from mere planks employing lower–skilled labor, rather than heavy timbers and more expensive carpenters and equipment, the lattice truss has also been constructed using many relatively light iron or steel members.

Suction caisson solution. Suction caissons (also known as suction buckets, suction piles, or suction anchors) are a new class of embedded anchors that have a number of economic advantages over other methods. They are essentially upturned buckets that are embedded into the soil and use suction, by pumping out the water to create a vacuum, to ...

Suction caissons (also referred to as suction anchors, suction piles or suction buckets) are a form of fixed platform anchor in the form of an open bottomed tube embedded in the sediment and sealed at the top while in use so that lifting forces generate a pressure differential that holds the caisson down.
