Abstract:
Based on load transferring concept, this paper puts up a new method which uses double broken line model to calculate the negative friction of pile. The paper establishes the equation about the friction and relative displacement according to elastic or plastic condition that soil around or on the tip of the pile lies in by the double broken line model. The negative friction, the position of neutral point and axel force of single pile can be defined based on relative displacement.
