雷电灾害风险评估模型在社区空间尺度上对雷击危险次数及脆弱性的模拟和分析

Simulation and analysis of number of dangerous lightning events and vulnerability on a scale of community: application of lightning disaster evaluation model

本文在5 m×5 m细微网格上实施了社区雷电灾害风险评估模型的开发及应用,对雷击危险次数及脆弱性进行了数值化评估模拟。社区雷电灾害风险评估实例应用表明:模型模拟出的评估结果能反映雷击风险在社区空间尺度上的差异,以及地形因素、防雷状况及附近建筑物"避雷针"效应等所产生的风险差异,结果较为合理。适用于雷电灾害风险规避及风险控制。

Development and application of lightning risk assessment model on a scale of comminity were implemented based on fine 5 m × 5 m grids,the numerical assessment simulation of number of dangerous lightning events and vulnerability was carried out. The case study of the lightning risk assessment on a scale of community indicates that the results assessed by the model may reflect the difference of lightning risk on spatial scale of community and the difference caused by terrain factor,lightning protectiveness and the lightning rode effectiveness of nearby buildings. The results assessed from the model are reasonable comparatively and suitable for evasion and control of lightning disasler risk.
