Evaluation of Working Load on Piles Considering Negative Skin Friction

부주면마찰력을 고려한 말뚝의 설계지지력 산정

A summary of the various techniques available to calculate negative skin frictions on piles is presented. In light of all these existing techniques, a simple method is recommended to calculate the negative friction based on strength of pile material, bearing capacity and pile settlement. An example is worked out and the results of a numerical analysis are highlighted.
