Abstract
Based on the constructed geomechanical model of the pneumatic borer and soil interaction and using the finite element method, the authors solve the problem on the stress state in soil enclosing a moving pneumatic percussion machine, considering variation of physico-mechanical properties of soil. The experimentally measured and calculated relative accelerations of acoustic field depending on the machine orientation in soil are compared.
