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 ...

Suction caisson installation in sand with isotropic permeability varying with depth [PDF]
Applied Ocean Research, 2013 Suction-induced seepage is pivotal to the installation of caisson foundations in sand. Indeed, the upward pore water flow on the inner side of the caisson wall causes a release of a fraction of soil resistance due to the reduction of the lateral effective stress.

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.

Design procedures for installation of suction caissons in sand
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2005 Suction-installed caisson foundations are being used or considered for a wide variety of offshore applications ranging from anchors for floating facilities to shallow foundations for offshore wind turbines. In the design of the caissons the installation procedure must be considered as well as the in-place performance.

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 penetration and extration of modified suction caissons in clay
Yantu gongcheng xuebao, 2020 A series of model tests are conducted to investigate the installation and extraction behavior of the modified suction casson(MSC) embedded in marine clay by taking the MSC dimensions, shear strength of clay and installation method into account.
