摘要:
Seismic events and wave action can induce volumetric strain ( ε v ) accumulation in saturated sandy soils, leading to damage to the ground surface and structures. A quantifiable relationship exists between the generation of ε v in sandy soils under drained conditions and the development of pore water pressures under undrained conditions. In this study, the impact of relative density ( D r ), cyclic stress path, and stress level on the characteristics of volumetric strain ( ε v ) generation in saturated coral sands (SCS) was evaluated through...
