NEGATIVE FRICTION "DOWNDRAG ON A PILE"
This summary report was prepared by Miss Karen Castellanos and Mr. Chien-Tan Chang of the Implementation Division. It is based on the videotape presentation made by Professors T. William Lambe and Mohsen M. Baligh of the Massachusetts Institute of Technology. It summarizes more than 4 years of research effort on negative skin friction. The primary objective of the research was to develop procedures for estimating the magnitude of pile downdrag and eliminating pile downdrag if it proves to be uneconomical in design considerations. The research, conducted by MIT, was sponsored by the Massachusetts Department of Public Works in cooperation with the Federal Highway Administration. The objective of this report is to provide interested engineers with a better understanding of the negative skin friction problem and a prediction method to be used in the design of pile foundations. A copy of "A Manual on Prediction of Pile Downdrag on End Bearing Piles" prepared under the above research, is included in the appendix for the convenience of the reader. /FHWA/
