Cyclic mechanical loading of unsaturated silty clay soils [PDF]

E3S Web of Conferences, 2020
Cyclic mechanical loading of soils due to natural causes such as earthquakes or due to loads coming from structures causes the accumulation of strains and excess pore-water pressures endangering the long term serviceability and stability of the structures built on them.
