Abstract
The mathematical model of vertical penetration of a steel pipe in soil with a shock pulse generator is described. The influence of the external problem parameters on the attenuation of the shock pulse propagating along the pipe is described, and the process generalities are found. The attenuation law of the mass velocity amplitude in the shock pulse along the pipe during vertical penetration in soil is revealed.
