Each parameter of pile and soil in marine sandy soil foundation is analyzed based on p-y curve method, including qualitative analysis and quantitative analysis. With engineering design index such as the displacement and deflection slope of pile top, max moment and max shear of pile shaft, max soil pressure to judge standard, we distinguish the sensitivity factors and the non-sensitivity factors. Research conclusions are as follows: the internal friction angle ϕ and the bending stiffness EI of pile are sensitivity factor, the effective unit weight γ is moderate sensitivity factor, and the effective unit weight γ is relative insensitive factor. Research results can provide beneficial reference for engineering surveyors and designers. © 2016 Taylor & Francis Group, London. Source
