The invention discloses a fractal method for predicting nonlinear permeation of saturated cohesive soil, which comprises the following steps of: constructing a nonlinear permeation fractal model of the saturated cohesive soil based on an initial hydraulic gradient of a microscopic permeation channel; and calculating to obtain seepage velocity predicted values of the saturated cohesive soil under different hydraulic gradients by using the nonlinear seepage fractal model of the saturated cohesive soil, and predicting the seepage state of the saturated cohesive soil under the different hydraulic gradients through the seepage velocity predicted values. The new saturated cohesive soil nonlinear permeation fractal model considering the initial hydraulic gradient of the microscopic permeation channel is provided, and the limitation of an existing nonlinear permeation model is solved; according to the model, continuous prediction can be carried out on non-linear permeation, the calculation steps of an existing non-li
