“…For example, lightning caused a 50 m long and 1 m wide breach in the ground in Yuncheng, Shanxi Province, China and caused a pothole in Batok Town, Bukit, Singapore (see Figure 1 and Figure 2 , respectively) [ 5 , 6 ]. Lightning struck buried pipelines in Alabama and Cideville, France, both causing pipeline leaks and posing a significant threat to pipeline transportation [ 7 , 8 ]. Lightning struck an airport runway on the west coast of India, causing damage to the runway as well as cracks to the roadbed [ 9 ].…”

A semi-analytical solution for forecasting the soil behavior induced by lightning strikes is of great engineering significance to calculate the radius of the soil plastic zone. In this paper, a simplified two-stage method is employed to solve the shock wave pressure and the radius of the soil plastic zone. The solution is verified against experimental data. Using the present model, the major factors dominating the shock wave pressure and the radius of the soil plastic zone are investigated. The results show that (1) the radius of the soil plastic zone (rp) induced by lightning decreases monotonically with cohesion (c) and internal friction angle (φ), while c has a better effect on soil properties than φ does; (2) increasing the initial radius of the plasma channel (ri0) can reduce the pressure (P) and increasing ri0 has a nonnegligible effect on rp; with ri0 increasing by 100%, the radius of the soil plastic zone increases by 47.9–59.7%; (3) the plasma channel length (L) has a significant influence on P and rp, especially when L is at a relatively low level; (4) the rp induced by lightning decreases exponentially with attenuation coefficient (a); (5) the wavefront time is a major factor while the half-value time is a minor factor for the shock wave pressure induced by plasma explosives.

“…Excessive voltage differences between the grounded and ungrounded components of a pipeline may cause ignition or even ablation-induced damage. The pipeline ablation accidents reported in the literature are generally caused by lightning strikes (Venturino, 2016; Pikas and Shoaf, 2010; Quickel and Beavers, 2011), and numerous studies have investigated the law of lightning strike-induced ablation (Metwally et al , 2004; Paisios et al , 2008; Liu et al , 2017; Chemartin et al , 2012). Studies have examined ablation pits on-site and those that were simulated in a laboratory, and they have revealed that ablation induces a considerable change in the microstructure and hardness of pit areas, which has a substantial effect on the mechanical properties of a pipeline (Li et al , 2020).…”

Purpose The purpose of this study is to elucidate the effects of electric-arc-induced ablation on the corrosion behavior of pipeline steel in neutral and high pH environments. Design/methodology/approach Electrochemical testing, an atmospheric-pressure immersion experiment and various techniques (e.g. scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy) were used to examine the effects of electric-arc-induced ablation on the corrosion behavior of pipeline steel in neutral and high pH environment. Findings Electric-arc-induced ablation occurred preferentially in areas of inclusion. The corrosion resistance of an ablation pit was lower than that of non-ablation areas. In the neutral soil solution, general corrosion was the dominant corrosion that affected pipeline steel; the effect of ablation was small but pitting corrosion could still be induced. In a high pH environment, the samples without ablation were passivated, whereas the samples with ablation pits could not be passivated; the ablation pits were likely to develop pitting corrosion. Originality/value Electric-arc-induced ablation can reduce the corrosion resistance of pipeline steel under high-voltage direct current interference.
