Investigation of the behavior of Liquid on Pressure in Buried Pipe under Blast

In this study, a parametric study on buried pipes under soil was performed as a result of blast loading. Effects of various parameters such as physical properties of water, oil, air, soil, pipe and T.N.T have been investigated. The arbitrary Lagrangian-Eulerian (ALE) method was employed using LS-DYNA software. The maximum pressure in a buried pipe explosive was seen when the angle was about 0° to 45° and the minimum pressure occurred when the angle was about 45° to 90°. Therefore, all figures in this study illustrate that pressure of fluid in buried pipes can help in stabilizing pipes.
