Abstract: Affected by geology and natural weather of dry and wet cycles, many slopes of expansive soil lead to the development of the fissures and finally became a block system. To take the slope of expansive soil as a block system in which soil blocks have constitutive relation of non-saturated soil, there are frictional and expansive forces between the blocks, and there is a feature of towed slide and effect of time and space. A new method of discontinues deformation analysis are formed for the slope stability analysis of the expansive soil. This method is used to analyze the stability analysis of some slopes of the expansive soil in a highway, and very good results are available.

Key words: expansive soil, slope stability, discontinuous deformation analysis
