Abstract:The effects of thickness and stiffness of pile cushion and hammer cushion on pile driving process were analyzed by GRLWEAP software, and the related laws were summarized, which provided important reference for feasibility evaluation of pile sinking in electric power engineering. Combining with practical engineering project, feasibility research on pile sinking was carried out by GRLWEAP before pile sinking, with selection of pile driving system, estimation of the parameters in the process of pile sinking, determination of the difficulty of pile sinking, to make the pile sinking work smoothly. Practice proved that the method was necessary and effective.
Keywords:prestressed highintensity concrete pile; GRLWEAP; pile driving system; pile cushion; hammer cushion
