摘要：

The authors use a two-dimension plane model to analyze seismic wave propagation in block-structured media under impulse loading. Dynamics of the medium is described by means of pendulum approximation, where blocks are considered incompressible and deformation and displacement occur via compressible intermediate layers. The simplest calculation model of a square lattice composed of masses and springs connected in axial and diagonal directions is under discussion in the article.
