摘要：This paper discusses the validation pore water pressure model calibration parameters of four stress-based models for prediction of pore water pressure generation for a non-plastic silt exposed to dynamic loading.The first model was developed by an empirical solution by Seed et al.[1].In the sequel,a simplified alternative model was proposed by Booker et al.[2].Three decades later,Polito et al.[3] revisited the method proposed by Seed et al.[1] with the help of statistics.Lastly,Baziar et al.[4] proposed an alternative closed form solution for silt soils with using statistical software based on Seed et al.’s [1] methodology.Generalized reduced gradient (GRG) nonlinear algorithm was used for regression analyses to establish correlations for several calibration parameters.Modified pore water pressure generation model parameters based on the silty soils are also presented in this paper.The results show that the calibration parameters of pore water pressure generation models for the Seed et al.[1],Booker et al.[2],Polito et al.[3] and Baziar et al.[4],differ significantly for silty soils.
