Guidelines for seismic spectral amplification are provided in current building codes based on soil strength/stiffness by means of seismic site class. However, current codes do not make a difference between fully saturated and unsaturated soil deposits and do not account for effects of soil heterogeneity on seismic amplification. This study investigates the effect of natural small scale soil het...

A method for computing slip-line fields in the case of cohesionless backfills with stress discontinuity was proposed. The potential failure zone is divided into Rankine and transition zone, rigorously determined using theory plastic mechanics. are then further a series triangular slices. On basis force moment equilibrium conditions typical slice, recurrence equation lateral established. Further...

In the presence of viscous and cohesive interactions between particles, a granular flow is governed by several characteristic time stress scales that determine its rheological properties (shear stress, packing fraction, effective viscosities). this paper, we revisit extend scaling arguments used previously for dry cohesionless flows suspensions. We show rheology can be in principle described si...

A p-y curve method of pile near cohesionless soil slope under reversed lateral load is proposed. This takes into account the failure mode around and interaction between soil, derives ultimate resistance pile. Considering change original stress state due to deflection foundation, influence relative density, initial mean effective foundation on internal friction angle sand evaluated further accur...

Footing foundations are sometimes built on sloping grounds of natural sand which is highly anisotropic. The anisotropic mechanical behaviour can significantly influence the bearing capacity a foundation and failure mechanism its supporting slope. Neglecting anisotropy may lead to overestimated under-design foundations. A numerical investigation response slope under strip footing presented, plac...

Jacket structures mounted on suction buckets carry potential as cost-efficient foundations for next-generation 10 MW+ offshore wind turbines located in transitional water depths. Given this foundation method, resistance to overturning moment relies mainly the axial response of buckets. In practice, bucket can be modelled “Beams Non-Linear Winkler Foundation” where soil is idealised non-linear s...
