Abstract: In this paper, the author considers the soil skeleton as Maxwell model, gives the Laplace transformation form of the settlement W（p）, when the load-distribution gives as cosine form. By considering the instantaneous and long-period behavior of the settlement, then gives W（p）some approximate form, by which W（t） can be found. When the loading is rectangular-distributed, for finding solution, an approximated Fourier integral must be worked, then gives the solution.
