Abstract Using the Laplace Transform，this paper analyzed the partially penetrated vertical drain with vacuum preloading. A three-dimensional virtual vertical drain is assumed to reflect the real three-dimension seepage in the soil beneath the tip of the vertical drain；moreover，the vacuum loss along the drain is also taken into consideration in the model. The parameters influencing the consolidation are analyzed，such as well-resistance，vacuum loss，the penetrating ratio etc.. Finally，the results are compared with the field data which are matched very well.

Key words： soil mechanics vacuum preloading partially penetrated vacuum loss the best penetrate ratio Laplace transform
