What doesn't make sense to me is the near horizontal lines at 21'-22' and 36'-37', indicating that the downdrag suddenly disappears once the pile is in the clay and reappears once the pile goes below the clay.

FOR AXIAL LOADS, DRAGLOADS, DOWNDRAG, AND SETTLEMENT ASCE and Port of NY&NJ Seminar1), April 22 and 23, 1998 Bengt H. Fellenius Urkkada Technology Ltd. Ottawa, Ontario. Introduction. Design of piles requires understanding of how load is transferred from pile to soil and, less obvious but equally important, from soil to pile.

value of about 200 lb/ft2. According to Fellenius, this value will adequately predict the downdrag load. Based on pile-uplift test results, Machan and Squier (2), mea sured 90 percent reduction in downdrag forces on bitumen-coated piles. When downdrag was predicted using bitumen viscosity, the forces were lower than the field measurements.

The authors' recognize that there are other failure modes, e.g., buckling, in addition to the axial pile conditions that should be considered in a comprehensive pile design.
