The invention relates to a method for inhibiting the swelling-shrinking property of swelling soil. An undisturbed method is adopted; the physical and chemical mechanism of the chemical property of lime and the clay mineral effect in swelling soil is utilized; gravel or a mixed material of break stone and lime powder is used as a material for inhibiting the swelling-shrinking deformation of the swelling soil; and a covering material is laid at the upper part of the gravel or the mixed material of break stone and lime powder according to the concrete condition of practical engineering so as to ensure that the gravel or the mixed material of break stone and lime powder can be moulded, and the effect is normally exerted. By adopting the method the swelling-shrinking property of the swelling soil can be inhibited under the condition that disturbance on the soil structure is reduced as much as possible, construction procedure is simple and following repair remedial measure is easier to implement.
