“…A number of tries for suction installation of the laboratory model tests, particularly in permeable soils, have ended in failure. Bang et al (2000) only achieved a maximum of 27.9 cm suction penetration in sand for a caisson of 150 cm long. Localised piping was mentioned to have caused a loss of vacuum and fluidisation resulting in the sand heave to develop within the caisson.…”

Some previous numerical investigations indicated that positively tapered suction caissons may provide pull-out capacities considerably higher than that of their equivalent upright caissons Zeinoddini et al 2008a;Zeinoddini et al 2008b;Zeinoddini, Hobbi, et al 2009;Zeinoddini, Keyvani, et al 2009).…”

Behaviour of upright suction caissons with regard to their applications, installation, load-bearing, etc., has already been investigated by a number of researchers. Some researchers have also addressed the behaviour of tapered piles under different loading conditions. However, there has not been any previous experimental experience regarding the performance of tapered suction caissons. This paper reports the results of a primarily experimental investigation intended as a first step to understanding the performance of tapered suction caissons. The 1g experiments have been carried out on small-scale caisson models having upright and sloping walls. The caissons have been installed in a very fine saturated silty sand, and the effects of geometrical parameters, wall slope and the soil density on the overall penetration force required for installation and the pull-out capacity of the cassion have been studied. Influence of pull-out rate on the ultimate capacities has also been investigated.

“…An innovative underwater permanent foundation system using suction piles was introduced in the offshore industry in recent years. A suction pile is an open-ended pile that is sealed at the top and installed by applying suction pressure inside the pile, which acts as an external surcharge to push the pile into the seafloor (1). Suction piles have been used extensively in offshore applications, because they can be installed easily in deep-water locations (2).…”

“…They may be retrieved later by applying a positive pressure inside the pile. The details of the suction pile with regard to its use, mechanism, installation, analysis, and design methods can be found in various references (1,(4)(5)(6)(7)(8)(9).…”

A series of centrifuge model tests was conducted to measure the ultimate horizontal bearing capacity of suction piles. Three different pile lengths were tested in sand. Model piles were laterally loaded at different points along the pile length to evaluate the effect of the loading depth on the ultimate horizontal bearing capacity of suction piles. Two tests were conducted for each loading point. Results from centrifuge model tests were then compared with the analytical predictions to determine the validity of the analytical solution in predicting the ultimate horizontal bearing capacity of rigid suction piles loaded at various depths. Predicted values from the analytical solution compared well with the measured values from the centrifuge model tests.
