Suction Caissons in Intermediate Soils

9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”, 2023
Suction caisson supported jackets have been used on several recent offshore wind farm projects in Europe including Aberdeen Bay, Borkum Riffgrund 2 and Seagreen. Suction caissons are particularly sensitive to soil conditions, including 'intermediate' soils such as partially drained sands, silts, and heavily interbedded sands and clays.

Relationships between leaf and root area indices and soil suction induced during drying–wetting cycles [PDF]

open access: yesEcological Engineering, 2016
The stability and serviceability of geotechnical infrastructure may be affected by plant-induced soil suction during drying-wetting cycles, because an increase in suction would reduce hydraulic conductivity and also increase shear strength.

Soil suction monitoring for landslides and slopes

Quarterly Journal of Engineering Geology and Hydrogeology, 2011
Rainfall is the most frequent triggering factor for landslides and the development of early warning systems has to take account of this. It is suggested that direct measurement of pore pressure gives the most reliable prediction of failure of a slope.

Measurement of Suction Stress and Soil Deformation at High Suction Range

Geotechnical Testing Journal, 2020
Abstract Suction stress is the effective stress independent of mechanical boundary conditions but is due to water content variation. It occurs on or near particle contacts and does not directly transfer through the soil skeleton and hence can only be and has been measured indirectly and deduced from soil’s strength or deformation.
