Method for determining hydrogeological parameters of nonlinear consolidation aquitard

The invention relates to the technical field of hydrogeological parameter measurement, in particular to hydrogeological parameters of a nonlinear consolidation aquitard. The technical problem to be solved by the invention is to provide the method for determining the hydrogeological parameters of the nonlinear consolidation aquitard. The invention discloses a method for determining hydrogeological parameters of a nonlinear consolidation aquitard. The method comprises the following steps: A, establishing an experimental model; b, saturating the experimental soil sample; c, carrying out an experiment; d, recording experimental data; e, terminating the experiment; f, parameter calculation: making an S-t actual measurement curve by using the recorded deformation S in a double logarithmic coordinate system with the same modulus as the standard curve, wiring with the standard curve, randomly selecting a matching point, recording corresponding coordinate values S and t, and calculating a consolidation coefficient Cw,
