Modeling of Seismic Impacts on the Main Pipeline

Abstract

In this article, a seismic calculation of a section of an underground pipeline is performed using the Ansys software package. The linear-spectral analysis of this calculation was based on the response spectrum obtained from a variety of real records of seismic ground vibrations at the Petropavlovsk seismic station. This method makes it possible to take into account the experience of past earthquakes, reducing the likelihood of exceeding the expected loads on the structure during a new earthquake. The results of the seismic calculation of the pipeline made it possible to form a complete picture of the distribution of stresses in the pipeline for various forms of the trench and the material of its backfill. A comparison is made of the maximum stresses in the pipeline for various methods of its seismic protection.
