sg-ntu-dr.10356-815312020-03-07T11:43:31Z Blast response and failure analysis of pile foundations subjected to surface explosion Jayasinghe, Laddu Bhagya Thambiratnam, D. P. Perera, N. Jayasooriya, J. H. A. R. School of Civil and Environmental Engineering Surface explosion Pile foundation 30 p. This paper presents the response of pile foundations to ground shocks induced by surface explosion using fully coupled and non-linear dynamic computer simulation techniques together with different material models for the explosive, air, soil and pile. It uses the Arbitrary Lagrange Euler coupling formulation with proper state material parameters and equations. Blast wave propagation in soil, horizontal pile deformation and pile damage are presented to facilitate failure evaluation of piles. Effects of end restraint of pile head and the number and spacing of piles within a group on their blast response and potential failure are investigated. The techniques developed and applied in this paper and its findings provide valuable information on the blast response and failure evaluation of piles and will provide guidance in their future analysis and design.
