摘要: Estimation of the drivability piles requires modelling hammer impact in order to provide input force wave at pile head. Historically, this has been achieved through a numerical model components (ram, cushion and anvil), which is then linked with that effect analysis. This paper presents an analytical impact, based on lumped ram anvil masses separated by internal damping, connected modelled as dashpot. Force–time responses derived from are compared actual field data, also results commercially available models impact. The used explore characteristics particular attention combinations parameters lead bounce and, hence, significant loss energy transferred pile.
