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.

Simulating the response of buried structures to external blast loads: Methods, challenges, and advances

“…publications in this field emphasize the safety of urban structures. Among the various applications of this topic are safety assessment of transportation and metro tunnels, 1 civil air defense tunnels, 2 urban utility tunnels, [3][4][5] underground pipelines, [6][7][8][9][10][11][12][13] culverts, 14 as well as safety assessment in excavations near the existing tunnels [15][16][17][18][19][20][21][22] or the extension of tunnels, [23][24][25] and safe storage of explosives. 26 These structures have different cross-sections depending on their function, design, and construction technology 27 as depicted in Figure 1A.…”
