Prediction method of soil permeability coefficient and related equipment

The embodiment of the invention provides a soil permeability coefficient prediction method and related equipment, which can reduce the test time of a dry density soil permeability coefficient and improve the calculation efficiency of the soil permeability coefficient. The method comprises the following steps: determining a standard pore permeability coefficient of a target dry density soil body; determining first pore size distribution information corresponding to a target dry density soil body and second pore size distribution information corresponding to a to-be-measured dry density soil body, wherein the to-be-measured dry density soil body and the target dry density soil body are different dry density soil bodies; determining a to-be-measured pore permeability coefficient corresponding to the to-be-measured dry density soil body according to a pre-constructed capillary tube permeability model, the first pore size distribution information, the second pore size distribution information and the standard pore
