Abstract In this paper, the application of the energy-based excess pore pressure generation model using damage potential to the assessment of liquefaction potential is examined through experimental and analytical investigations. For a more realistic description of the dynamic responses of saturated sands, the model parameters of the proposed model were modified based on the relative density. Dynamic undrained triaxial tests were performed for sand with different relative densities. Based on the test results, new equations for the model parameters with the relative density were addressed. Further, a liquefaction potential assessment procedure using the model based on the maximum cumulative excess pore pressure ratio is also proposed. Factors of safety calculated from the stress-based method and the proposed method were compared through examples with different soils and earthquake conditions.
