EVALUATION OF ENERGY-BASED FACTOR OF SAFETY AGAINST LIQUEFACTION
抄録(英):
The factor of safety against liquefaction of saturated soil is defined: F■ = ■(■/■) where ■ is the strain energy increament in the pore-water due to the plastic deformation of the skeleton and ■ is the increament necessary to cause liquefaction. A pair of material constants, namely energy absorption ratio and dynamic internal friction angle, are introduced to express the strength of soil against liquefaction. A procedure is developed to evaluate F■ from strong motion parameters and is verified by the case study of the Wildlife Liquefaction Array.
