| Abstract: | A construction process of long-bored pile in deep loess is introduced simply.Through the mechanical analysis to the pile foundation in the special process of construction,it is concluded that the negative friction of long-bored pile from collapsibility of loess has contribution to the late bearing capacity of pile. |
