Pile Downdrag During Construction of Two Bridge Abutments

Two steel pipe piles in place in abutments for two different bridge constructions sites were instrumented with strain gauges to measure the magnitude of negative skin friction. The piles were monitored before, during and up to 19 months after construction was completed. The load versus depth and tim...

The piles were monitored before, during and up to 19 months after construction was completed. The load versus depth and time in each pile is discussed. Maximum observed dragloads ranged from 98 to 127 kips. A comparison with two methods for calculating dragloads is presented. Both comparison methods were found to be conservative, with the Briaud and Tucker (1997) approach more closely estimating the observed load versus depth behavior. 2008-10-08T07:00:00Z text application/pdf https://scholarsarchive.byu.edu/etd/1918 https://scholarsarchive.byu.edu/cgi/viewcontent.cgi?article=2917&context=etd http://lib.byu.edu/about/copyright/ All Theses and Dissertations BYU ScholarsArchive downdrag dragload negative skin friction Civil and Environmental Engineering
