Solid-Fluid Coupled Numerical Analysis of Suction Caisson Installation in Sand

Journal of Marine Science and Engineering, 2021
Suction caissons are widely used foundations in offshore engineering. The change in excess pore pressure and seepage field caused by penetration and suction significantly affects the soil resistance around the caisson wall and tip, and also affects the ...

Penetration and Pullout Capacity of Low-Skirted Suction Caissons [PDF]

Shock and Vibration, 2021
The bearing capacity of suction caissons is the key to the design of offshore structures. A new type of cross-shaped low-skirted suction caisson is invented to effectively improve the bearing capacity, considering inevitable “soil plug” phenomenon.

A standard formulation for the installation of suction caissons in sand

Journal of Ocean Engineering and Science, 2019
Suction assisted installation of caisson foundations in sand relies on the developed seepage around the caisson wall. Seepage is known to produce soil loosening inside the caisson cavity and an overall reduction in soil resistance to caisson penetration.

Model Tests on Influence Factors on the Pullout Behavior of Suction Caisson in Stratified Soils

Advances in Civil Engineering
As offshore wind power constructions expand into deep waters, suction caissons have gradually become the preferred foundation. The controlled load of the suction caisson for the deep-water wind turbine is the pullout load.

Bearing behavior and accumulated rotation of modified suction caisson (MSC) in saturated sand under cyclic loading

Rock and Soil Mechanics, 2021
Modified suction caisson is a new type of suction foundation for offshore wind power engineering. Model tests were carried out to investigate the variation of cumulative rotation angle and its influencing factors of the regular suction caisson (RSC) and

Impedance of flexible suction caissons [PDF]

Earthquake Engineering & Structural Dynamics, 2007
AbstractThe dynamic response of offshore wind turbines is affected by the properties of the foundation and the subsoil. The aim of this paper is to evaluate the dynamic soil–structure interaction of suction caissons for offshore wind turbines. The investigations include evaluation of the vertical and coupled sliding–rocking vibrations, influence of the

Stress-seepage coupled analysis of critical suction for installation of suction caissons in sand

Yantu gongcheng xuebao, 2021
The critical suction is the key control factor for the installation of suction caissons in sand. The existing methods mainly rely on seepage analysis to determine the critical suction, which does not consider soil deformation and consequently might not ...

Model tests on uplift bearing capacity of gravitational reinforced composite suction caisson foundation

Yantu gongcheng xuebao, 2020
As the anchoring foundation of the tension leg platform (TLP), the suction caisson foundation is mainly subjected to the vertical pullout loads. The uplift bearing capacity of caisson is only composed of the internal and external frictions and caisson ...
