Relationship between pore water pressure and dissipated energy of fiber-reinforced sand

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Under the loading of earthquake, sandy soil is prone to liquefaction and resulting in the superstructure damage. Therefore, the liquefaction identification of sandy soil is the primary task of liquefaction disaster prevention. Based on the energy dissipation method, the relationship between pore water pressure (u) and dissipated

EFFECT OF CHANGE IN THE COEFFICIENT OF PERMEABILITY ON CONSOLIDATION CHARACTERISTICS OF CLAYS

Journal of Engineering, 2023
The settlement rate and pore water pressure dissipation rate are mainly controlled by the permeability of soil. Both laboratory and field tests show that the permeability is varied during the loading and consolidation process.
