Effects of initial static shear on cyclic resistance and pore pressure generation of saturated sand

K Pan, ZX Yang - Acta Geotechnica, 2018 - Springer
In practical engineering, cyclic shear stresses induced by earthquakes, traffic, and waves
are superimposed on the initial static shear stress in sand fills or deposits, leading to …

An experimental study on the apparent viscosity of sandy soils: from liquefaction triggering to pseudo-plastic behaviour of liquefied sands

L Mele - Acta Geotechnica, 2022 - Springer
The complete loss of soil strength and stiffness, which occurs during soil liquefaction, marks
a change of state of the soil that switches from solid to liquid. In particular, several …
