Abstract Based on macroscopic equivalent model theories and the microscopic analytical theories，the properties of wave propagation in the polyphase soil-stone mediums are studied. The effective bulk modulus and effective shear modulus of the polyphase soil-stone mediums are derived by using the equivalent fluid model，particulate contact theory，and Gassmann¢s equations. Then，the theoretical calculation formulae of wave velocity are proposed by assuming that the polyphase soil-stone medium is made of a homogeneous，isotropic，and linearly elastic material containing polyphase soil-stone composite medium. The theoretical calculating results show that the wave velocity has close relation with dry density，soil-stone ratio，water content，depth，saturation degree，and grain diameter of polyphase soil-stone medium.
