【Abstract】 Three cases of negative friction were taken into account for the pile body. The calculation method for negative friction of pile body is analyzed and two requirements that the bearing capacity of the pile should meet with consideration of negative friction are pointed out. A discriminant for determination whether the negative friction has impact on the bearing capacity of the pile is suggested to reduce such impact on bearing capacity of the pile.更多还原
