It is no doubt that the effect of water pressure and of water movement through the pores in geologic materials is of great practical importance. However, the realistic problem in the hydrogeologic modelling has not been analysed until the powerful numerical techniques such as FEM are invented. Solution methods f or three dimensional problems are still the big subject to be explored. In this paper a new quasi-three dimensional method (vertical slice method) to analyse groundwater problems is proposed. A medium is modeled by anassemblege of arbitrary numbers of vertial or inclined slices which are connected each other by one- or two-dimensional elements. Each slice is discretized by the usual two-dimensional finite element mesh. The whole system is solved by iteration process. The new method is evaluated by comparing with an analytical solution and is applied to the problem of flooding in tunnel excavation.
