Investigation of influence the pressure and stress on the water in buried concrete pipes in the different soil under blast loading (Review)

Soil mantle is an effective factor in decreasing damege against explosion so, by increasing the density of the soil, the pressure and the stress on the buried pipe increased. In this research, a parametric study on the buried pipe in the soil and due to blast loading have been performed. Effect of various parameters such as physical properties of water, air, soil, concrete pipe and T.N.T have been investigated. The arbitrary Lagrangian-Eulerian (ALE) method has been used by the LS-DYNA software. The pressure on the pipe and the stress in the important point of the pipe have been obtained
