Abstract: Based on the ADTD lightning location data in the Beijing-Tianjin-Hebei region from 2008 to 2018, this paper uses the line corridor grid method to study the spatiotemporal variation characteristics of ground lightning frequency, density, lightning current amplitude, and steepness along the Beijing-Tianjin intercity railway. The entropy weight comprehensive evaluation method is used to establish a lightning hazard model and reveal the risk levels in different sections.. The results indicate that along the Beijing-Tianjin intercity railway, negative (positive) ground lightning occur most frequently in August (June), with a bimodal (unimodal) structure in daily variation. The distribution of negative ground lightning current amplitudes are concentrated, mostly appearing in the 10, 30) kA range. The positive ground lightning current amplitudes are more dispersed, but a higher proportion occurs at high intensities. Both positive and negative ground lightning current steepness distributions are relatively concentrated, predominantly occurring within the 3, 12) kA·μs⁻¹ range. The ground lightning density along the Beijing-Tianjin intercity railway generally exhibits a spatial distribution pattern of "increase-decrease-increase-decrease", with the most susceptible sections to ground lightning occurring at the Beijing-Tianjin-Hebei border. The lightning current amplitude shows a pattern of "higher in the north and lower in the south", with high value areas for negative (positive) ground lightning appearing in the north-central parts of the Beijing section (from Beijing section to the northern part of Tianjin section). The negative (positive) ground lightning current steepness generally follows a pattern of "higher in the north and lower in the south" ("high-low-high-low") ,with high value areas occurring in the north-central parts of the Beijing section (the northern part of Beijing section and the southern part of Beijing section to the central-western parts of Tianjin section). The lightning dangerous level along the Beijing-Tianjin intercity railway gradually decreases from the Beijing section to the Binhai section, with high-risk sections mainly located in the north-central parts of the Beijing section.
