Abstract
From the mechanism of the formation of the negative friction in pile foundation,the paper illustrates the negative influence of the negative friction on the pile foundation,introduces the influential factors of the depth of the neutral points and its calculation methods,all kinds of calculative methods of the negative friction,and the consideration on the loading force calculation of the negative friction,has the analysis of examples and calculation,and introduces the project optimization measures to reduce the negative friction,and provides the summery and expectation of its research tendency.
