Dynamic Stress-Deformed States of a Circular Tunnel of Small Position Under Harmonic Disturbances

There are many underground tunnels of various shapes located in seismically active areas that need to be protected from seismic impacts. The paper considers the impact harmonic waves on a cylindrical shell viscoelastic half-plane. study's main purpose is determine stress-strain state when exposed waves. basic equation viscoelasticity displacements with corresponding boundary conditions obtained. problem posed solved mixed potentials satisfy wave complex parameters. solution expressed terms special Bessel and Hankel functions. As result multiple reflections, system algebraic equations coefficients In future, this by Gauss method selection element. analytical obtained infinite series, convergence which investigated numerically. numerical results were using MATLAB software package. reliability research confirmed good agreement theoretical experimental those other authors.
