THE MEASUREMENT AND CALCULATION OF NEGATIVE SKIN FRICTION FOR PILES IN COLLAPSIBLE LOESS |
| |
| Abstract: | In this paper, the shaft force measurements of 4 large diameter belled piles during the immersion test of
collapsible loess are introduced, The measured and calculated values for negative skin friction of piles are
compared. And finally, the check method of pile bearing capacity with negative skin friction is suggested. |
