Analysis of the Effect of Explosion on Altering the Tensions and Strains in Buried Water Pipes

Abstract

Pipelines that are buried in ground are used for transference of water and energy sources. These lines are considered infrastructures and have a high importance. In this paper behavior of soil and pipes are simulated using the finite-element based software ABAQUS, and effect of blast wave on the amount of tension and displacement of a pipe is investigated. The simulations are run for the pipe’s substance, burial depth, dimension, and also the intensity and situation of the explosion. AUTODYN software is used for evaluation of blast wave’s power. Simulation results show the positive effect of increasing the pipe’s dimension and burial depth on reducing the destruction caused by explosion.
