Abstract: For the negative force along rigid pile under embankment loads, an elastic differential equation is established. The ground settlement with depth and time is derived from Terzaghi’s consolidation theory; and its distribution is supposed as one mode. The analytic solution for the pile in the homogeneous ground under embankment loads is derived. An engineering example is studied by this method; and all influential factors are discussed respectively.

Key words: negative friction, rigid pile, embankment loads, axial force
