摘要: Abstract We study the propagation of transient waves under action a vertical step point load on surface half-space filled by block medium. The medium is modeled square lattice masses connected springs in directions axes x , y and diagonal directions. problem solved two methods. Analytically, we obtain asymptotic solutions vicinity Rayleigh wave at large time intervals. Numerically, solution for any finite interval. compare these with each other to Lamb an elastic
