Negative skin friction resistance most possibly exists in piles engineering. Technology of PCC pile is a new ground improvement technology developed independently by Hohai University. Study on negative skin friction of PCC pile hasn’t been carried out. Combined with the previous results and the property of PCC pile
based on Terzaghi consolidation theory
mechanism of negative skin friction of PCC pile has been studied. The results indicated that the negative skin friction doesn’t exist on plug and outside negative friciton can be calculated by previous methods. Differential equation is concluded but it is needed to be proved by tests.
