摘要:
下行先导发展过程中,建筑群不同位置场强的分布是决定雷击位置的重要因素,建筑物尖端周围由于自身静电场影响更易形成较为明显的电场变化趋势,相对等较低建筑物更易触发上行先导,仿真通过分析建筑物周围电荷聚集特性、电场空间分布以及建筑物大地附近积累电荷分布特性,得出高层建筑出现电场畸变对下行先导发展的“顶部优势”以及雷暴云位置在影响建筑物顶部电场分布的关键效果。
Abstract:
Field intensity distribution is an important factor of Buildings in different position to determine lightning location in downward leader development process, because of its own electrostatic field influence, the formation of cutting-edge position in building usually shows significant change in the electric field, so relatively higher buildings are more likely to trigger the upward leader. By the simulation of the charge gathered around the building characteristics, spatial distribution of electric field distribution features of the buildings, the accumulation of charge near the earth, it can be summarized that the key effect of the electric field distortion in the high-rise buildings on the “top edge”, and the location of the thunderstorm have significant effect on the electric field distribution at the top of the building.
