A series of field tests are described in which instrumented open-ended and closed-ended model piles were jacked into soft clay. The radial stresses, pore pressures, and load distribution were recorded throughout installation, equalization, and load-testing. Although the total stress and pore pressure developed during installation were related to the degree of soil plugging, the radial effective stress that controls the shaft resistance was shown to be independent of the mode of penetration. The long-term shaft capacity of the open-ended pile was closely comparable to that developed by closed-ended piles, suggesting a limited influence of end condition on the fully equalized shaft resistance. In contrast to the shaft resistance, the base capacity was highly dependent on the degree of plugging.||Type of material:||Journal Article||Publisher:||ASCE||Journal:||Journal of Geotechnical and Geoenvironmental Engineering||Volume:||137||Issue:||11||Start page:||1090||End page:||1102||Copyright (published version):||2011, American Society of Civil Engineers||Keywords:||Foundations; Piles; Open-ended penetration; Radial stresses; Instrumentation||DOI:||10.1061/(ASCE)GT.1943-5606.0000528||Language:||en||Status of Item:||Peer reviewed|
