...Vahdat Samandar Ajirlou; Jian Deng In this paper, the stochastic dynamic stability of pile foundations is investigated under multiple axial loadings along with soil pressures, extending traditional analyses that typically consider only one or two excitations. The system is modelled...

... the installation corridor. Because a DEA is a mobile foundation that penetrates along a long, curved trajectory, unlike fixed foundations (e.g. suction anchor) that occupy a small footprint, developing a robust ground model along the entire anticipated path is essential. Complementing the geophysical programme...

...N. Ntritsos; I. Anastasopoulos; G. Gazetas Results of a three-dimensional finite-element study for the effect of embedment on the undrained bearing capacity, the elastic stiffness, and the cyclic behaviour of square-in-plan foundations are presented. Uniaxial horizontal (Q) and pure-moment...

... foundation stability hard to assess reliably. It is usual to apply high safety, or strong material reduction, factors in foundation design. However, over-conservatism can lead to undesirable environmental and financial costs. This paper describes full-scale field tests conducted on peat, with and without pre...

Beyond these loads, at greater footing settlements, or soil rigidity, the Prandtl mechanism is shown to be the most appropriate. bearing capacity clays foundations plasticity...

...H.E. ACOSTA-MARTINEZ; S. GOURVENEC; M.F. RANDOLPH Environmental and buoyancy forces impart overturning moments and potentially direct uplift to offshore foundation systems. Shallow skirted foundations are an attractive design solution, as negative excess pore pressures developed within the soil...
