AbstractTwo 270-ft. long end bearing pipe piles filled with reinforced concrete and a 160-ft. long hollow steel pipe friction pile driven through a 30-ft. high highway embankment founded on compressible marine clay at Berthierville, Quebec, Canada, were intrumented to measure the build-up of negative skin friction loads due to consolidation of the foundation soil. The observations indicate that skin friction is related to the effective stresses in the soil. The paper is a progress report of observations made in the field to the end of 1969.
