“…It was assumed that those records that did not report their cover depth have a reference cover of 0.9144 m. This is not a strong assumption considering that the cover depth can be as many as two times the pipeline diameter (Mokhtari & Alavi, 2015). The records reported herein have a mean relation of 1.8D p and more than 70% reported a cover depth less or equal to 2D p .…”

“…The study of buried pipes that can be destroyed by earthquakes or explosions has been studied by Newmark [1] and M. Mokhtari. et al [2], M. Hajiazizi et al [3], O, Adibi et al [4] Esparza et al [5] developed an explosion analysis method to obtain simple methods necessary to determine the maximum stresses and pressures in underground steel pipes. The methods of Esparza et al [5] applies to the design of pipes that can be subjected to explosions.…”

“…Lagasco et al [12] studied the influence of explosion tunneling on an adjacent buried pipeline and proposed a design chart related to distance from the explosive source, media, the backfill layer and pipeline material characteristics. Recently, Zhang et al [13], Ji et al [14], Wang et al [15] and Mokhtari et al [16] carried out a parametric study on the response of buried steel pipelines with plastic deformation during intentional explosions. In this article, a time history method of directly pressuring the charging cavity was used to calculate the blasting cavity radius, and specific parameters of pressure time history were obtained according to the U.S. army technical manuals TM5-855-1 [17].…”

For non-conservative systems consisting of elastic-plastic material, dissipative damping of a system in a dynamic environment involves two parts: (1) the dissipative energy related to the velocity of the mass point and (2) the dissipative energy associated with the strain rate. In this paper, the dynamic response of buried high-pressure gas pipeline under blasting load is studied, where, dissipation of energy is explicitly considered. The dissipative work was introduced into the Lagrange function. According to the Hamilton principle and finite element theory, a non-conservative explosion model composed of elastic and plastic materials was established to identify the dynamic response and the propagation characteristics of a detonation wave in the earth medium, where the explosion cavity with a triangle pressure time history on internal wall was used to describe the explosive stress from blasting buried gas pipeline. In the scheme of modeling, 15 cases of different explosive payloads, different distances from the explosion center and different wall thicknesses of the pipe were regarded as the generalized load were carried out. Then the specific dynamic responses of pipeline under blasting load were shown in the post processing, as well as the relationship between peak particle vibration velocity and explosion distance and payload. Using three types of limit analysis methods, the critical explosive loading, critical blasting center distance and critical wall thickness of a buried high-pressure gas pipeline under blasting loading were determined. The computational method and results in this paper could be referenced for security operation of a buried pipeline and blasting construction scheme.
