Abstract  Taking an overseas project as an example， this paper introduces the geological stratification， soil resistivity， and sulfate content of the project， and determines that the project site has a certain degree of corrosiveness. Based on geological investigation data， pile structure options such as pre-stressed pipe piles， concrete bored piles， and rotary excavation for piling were fully taken into consideration， and relevant calculations were conducted. The optimal pile foundation scheme was proposed by comprehensive comparison and selection.

Keywords  rotary excavation for piling; bored cast-in-place piles; pre-stressed pipe piles; pile foundation detection; pile foundation construction
