%X On the basis of m-method in subgrade-reaction theory,horizontal pile displacements are expressed by beam-functions,and the influence of the skin frictional resistance along the pile on stability of end-bearing pile is discussed. The effect of positive and negative skin friction on equivalent length is shown. The calculated results indicate how load transfers along the pile and the negative friction has essential influence on pile stability. So the practice of ignoring the negative friction is dangerous.
