Diyorbek A Bekmirzaev, Tursunbay R Rashidov

Abstract


System of equations, which determines oscillations of linear pipeline interacting with surrounding earth medium under arbitrary direction of seismic effect is derived in the paper on the basis of Hamilton–Ostrogradsky’s variation principle. Numeric realization of the problem with given concrete low of soil seismic motion is carried out.
