The two-dimensional consolidation in saturated soil around sunk pile is studied. Considered the initial distribution and boundary condition of excess pore water pressure caused by setting pile
the series solution can be found by using methods of mathematical physics. The comparison between the calculation values and the consolidation degree values which are deduced from the practical bearing capacity shows that the series solution is reasonable. On the other hand
the consolidation degree results from the series solution can also be used to predict the capacity of the pile.
