Abstract The frozen porous media recently attract a great deal of attention in the field of the geophysical exploration as follows. Most of the studies on wave propagation in frozen soil have focused on the interface between one or two media. In order to reflect the propagation law of SH wave in frozen soil more intuitively，based on the wave theory of frozen saturated porous media，this paper establishes a free-field model of a saturated frozen soil overlying bedrock under the incidence of plane SH wave. Combined with the Helmholtz theorem，an analytical expression for the propagation velocity of SH wave in saturated frozen soil is obtained by establishing the dynamic stiffness matrix. The influence patterns of incidence angle，incidence frequency，cementation parameters，porosity，temperature and contact parameters on the propagation velocity of SH wave were analyzed. The results show that the propagation velocity of SH wave increases significantly with the increase of cementation parameters and contact parameters. The propagation velocity of SH wave gradually increasing with increasing porosity and temperature overall. The incidence angle of the SH wave has a significant effect on its propagation velocity，which varies nonlinearly with the increase of the incidence angle. There are corresponding peak velocity frequencies for different incidence angles with varying parameters. Most of the acceleration of the dynamic response is concentrated in the high incidence frequency band.
