Computer simulation of underground blast response of pile in saturated soil
چکیده انگلیسی

This paper treats the blast response of a pile foundation in saturated sand using explicit nonlinear finite element analysis, considering complex material behavior of soil and soil–pile interaction. Blast wave propagation in the soil is studied and the horizontal deformation of pile and effective stresses in the pile are presented. Results indicate that the upper part of the pile to be vulnerable and the pile response decays with distance from the explosive. The findings of this research provide valuable information on the effects of underground explosions on pile foundation and will guide future development, validation and application of computer models.


► This paper uses a multi-material computer model to study blast response of pile.
► The model involves air, soil, explosive and pile with appropriate material models.
► Present computer simulation results agree well with those from experiments.
► Findings will aid future developments and applications of computer simulations.
