Abstract
In this paper we propose a method for assessing the impact of blasting operations in the pipeline, which is based on mathematical modeling of the joint fluctuations of pipeline and soil during the passage of seismic waves from blasting. The calculation was performed in a plane problem, the soil was modeled Winkler elastic foundation, piping – a geometrically nonlinear shell. The numerical implementation was carried out using an iterative algorithm.
