Abstract Water pressure test is a special type of groundwater flow test with feature of short duration and test segment. The mathematical model of water pressure test with steady-pressure and non-stationary three-dimensional flow is proposed by considering the segment action as superposition of numerous point-source actions. The hydrogeological parameters are determined by using water pressure test. Even in the Lugeon¢s packer permeability test，a test of non-stationary flow is still useful. By using the observed data corresponding to time and flow，the hydro-geological parameters can also be obtained by the proposed method.
