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.
The approach is considered according to seismic stability of pipelines at conducting explosive works borehole charges or at influence of natural earthquake. In this paper independence of fluctuations of support of the pipeline is considered also.
