Buried pipes are the most important components of vital arteries used to distribute water, gas, oil, etc. The
experiences of past wars support the view that the invading country is devoting its attention to the bombing
and destruction of vital centers. Gas transmission pipelines as one of the most important transmission arteries
during wartime in the event of damage can cause serious financial and environmental damage. In this paper, the
method of reinforcing the pipe with FRP composite has been investigated. For this purpose, while preparing a
three-dimensional model of soil-pipe-composite system, to study the effect of factors affecting tube behavior
including composite material, composite thickness on tube deformation capacity according to the ALA regulation
was investigated. The soil is modeled using Solid and CFRP 3D elements and a Shell element pipe and is excluded
from the pipe separation and CFRP. For parametric studies, analyzes were performed using finite element
method using ABAQUS 6.10.1 software. Studies for 4, 12 inches with a depth of 1 m, the cost of explosion 15, 30,
45 kg, carbon composite and glass, angle of twisting 0, 30, 60, 90 degrees composite around the tube, composite
thickness 2, 4, 6 and 8 Mm was done. The results show that the use of carbon composite with the desired thickness
and angle of twisting has a good effect in order to reinforce the pipe against the threats.
