Numerical Analysis of Drivability of Non-Uniform Piles

摘要: This paper presents a numerical analysis of pile driving for tapered piles using FLAC software. The approach involves idealization pilesoil system in drivability. is assumed to be vertical and have elastic linear behavior. soil elastoplastic material which obeys the Mohr-Coulomb failure criterion. To allow slip between driving, interface elements are used at pile-soil borders along shaft toe. Quiet boundaries considered lateral directions absorb traveling waves. obtained results compared with experimental results, leading satisfactory agreement. It will shown that increasing angle taper, stresses decrease permanent toe settlement increases. These interesting phenomena on safe side driven piles.
