| Abstract: | This paper analyzed the cause of negative skin friction on piles in soft soil.Research progress on this topic was briefly summarized.Field data of typical down-drag force on piles were collected,and several authentic cases of engineering failure due to negative friction on piles were cited.Current methods of predicting negative friction and down-drag force on piles were discussed.Ten urgent problems for further study were listed and approaches for their solution were proposed.It is expected this paper provided some lines of approach for future study on similar subjects. |
