The invention discloses a method for calculating the relative permeability coefficient of unsaturated soil. The method comprises the steps that a certain initial void ratio e0ref is selected as a reference state according a soil sample of a certain type, van Genuchten SWCC equation parameters a1 and b1 are calibrated through an SWCC in the reference state; a parameter zeta is calibrated through an SWCC when the initial void ratio of the soil sample of the type is e0*; based on the calibrated parameters a1, b1 and zeta, the SWCC of the soil sample of the type under the condition of any initial void ratio e0 can be predicted; based on the SWCC under the condition of the initial void ratio e0, corresponding van Genuchten SWCC equation parameters a2 and b2 are obtained through secondary fitting and substituted into a relational expression for calculation, and therefore the relative permeability coefficient kr of the corresponding unsaturated soil can be obtained. By the adoption of the technical scheme, the difficulty in directly measuring the permeability coefficient in an experiment can be effectively overcome, so that consumption of manpower, material resources and time is reduced, meanwhile the workload in practical engineering is reduced to a great extent, and the job schedule is effectively improved.
