Behavior Of Pipe Piles In Sand: Plugging And Pore-Water Pressure Generation During Installation And Loading

A comprehensive overview of a geotechnical engineering study investigating how installation effects, such as pile plugging and pore pressure buildup, influence the axial capacity of pipe piles in sand. The monograph critiques current practices, specifically reviewing deficiencies in existing API design guidelines related to predicting pile behavior in sand. To address these gaps, the bulk of the research focuses on the development of sophisticated experimental facilities, including a dedicated pressure chamber and a specialized, high-frequency electro-pneumatic laboratory pile hammer. Crucially, the methodology relies on a newly engineered instrumented double-wall pipe pile to precisely measure internal and external stresses and pore water pressures during installation and subsequent loading. Furthermore, the text details the selection of Oklahoma sand as the testing medium and validates that the apparatus satisfies essential similitude and scaling laws required for meaningful model tests. This detailed work serves as a practical guide for developing the necessary laboratory equipment to advance the understanding of complex pile-soil interaction mechanisms.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/civil_engineering_made_simpleProduced by:https://www.podcaistudio.com/
