This paper presents a solution for partially penetrated prefabricated vertical drains (PVD) with less computational time and more accuracy than previous analytical solutions. A new impermeable boundary region at drain’s end is introduced to simplify boundary conditions and reduce the number of variables. Moreover, Laplace transform technique is utilized in this solution which could help to estimate smooth excess pore pressures with depth even in the early stage of  consolidation. Results of the new modified solution have been verified against results of the current literatures. A case study by vacuum consolidation technique is presented to verify the current solution. Excess pore water pressure in the soil and the drain and are well agreement with the proposed solution. Derived degree of consolidation from field settlements shows not much differences than current approach. Those verifications indicate that the proposed solution is an effective tool in solving the consolidation problems of partially penetrated vertical drain
