"Fractures and layering in rock masses have a large impact on both the\r\nmechanical and hydraulic properties of the rock mass. When considering seismic elastic\r\nwaves, fractures can also trap and guide waves and the behavior of such waves may prove\r\nuseful for probing the geometrical and mechanical properties of the fractures. In the longwavelength\r\nlimit, when the size of the seismic wavelength is much larger than the layer\r\nand/or fracture spacing, the propagation velocity is obtained by the effective medium theory.\r\nHowever, when the wavelength becomes smaller, a dispersive behavior is obtained that may\r\nbe significantly affected by the layer and fracture spacing.\r\nIn the proposed paper a dynamic homogenization technique proposed by the Authors to\r\nanalyze dispersive waves in periodic elastic materials (Bacigalupo & Gambarotta, 2012) is\r\nrevised and extended to the analysis of dispersive waves in periodically layered fractured\r\nrock masses. The obtained results for some material meso-structures by means of the\r\nproposed approach are compared to those ones by the rigorous Floquet-Bloch theory.\r\nFinally, some examples representative of rock masses are presented and discussed."^^ .
