To further study the unsaturated permeability coefficient of rock and soil masses, a model device for field testing the unsaturated permeability coefficient of rock and soil masses was developed, and a mathematical expression for field testing the unsaturated permeability coefficient was derived. By comparing and verifying with the test results, the results showed that the unsaturated permeability coefficient obtained from the field test of the device was very close to the existing test results and had a high accuracy. The device established in this paper can accurate determine the unsaturated permeability coefficient of rock and soil masses in the field, which has certain application value in engineering practice.
