城市区域地震次生火灾危险性评估
|
摘要
分析了影响地震次生火灾危险性的各项因素指标,利用层次分析法得到各因素的影响权重,结合G IS空间分析及数据处理能力对各个区域网格的各种影响因素进行评分,得出城市区域地震次生火灾危险等级的划分,为判断震后城市火灾高危险区域及评价地震后城市消防安全状况提供依据。
The paper analyzes each factor index which may affect risk of post-earthquake fire.Then gets influence weight of each factor by AHP.Risk classification of post-earthquake fire in urban region is put forward by taking advantage of spacing analyzing and data handling capacity of GIS to analyze and assess the various influence factor of each region grid.The realization of risk assessment of post-earthquake fire will offer forceful bases for the hign hazard area judgement and the accurate fire security condition assessment of post-earthquake fire in city.
