英文摘要	Theoretical analysis of a two-dimensional elastic foundation wave impeding block (WIB) seismic isolation system was conducted. First, based on the theory of elastic mechanics, the governing equation of the rectangular wave impeding block in the two-dimensional elastic foundation was established. Then, based on the incident of plane SH wave and the continuity condition between wave impeding block and half-space interface, the analytic solution of vibration isolation performance for the two-dimensional foundation wave impeding block was obtained by the wave function expansion method. In the end, according to the variation of amplitude attenuation coefficient, the influence of the shear modulus of wave impeding block, the depth of wave impeding block and the incident angle of elastic wave on the vibration isolation effect was analyzed. The results show that, the vibration isolation performance is improved obviously with the increase of shear modulus of wave impeding block; the vibration isolation effect for surface displacement increases gradually with the depth of wave impeding block; the smaller the incidence angle of elastic wave is, the more obvious the vibration isolation effect is. © 2019, Editorial Office of Journal of Vibration and Shock.
