基于模糊数学理论,利用AHP法建立影响评价对象雷灾风险的因素集并确定各因素的权重。在此基础上,将评价对象雷灾风险状况划分为安全、基本安全、危险、极度危险4个等级,并邀请建筑雷灾风险评估专家对各影响因素进行测评定级,进而计算出每个指标的隶属度,实现了雷灾风险评价由定性向定量的转化,建立了既有普通建筑雷灾风险多级模糊综合评价模型。为了验证该评价模型的评判效果,选取东莞某科技研发大楼进行雷灾风险评判,将评判结果与《雷电防护第2部分:风险管理》(GB/T21714.2—2008)评判结果对比,二者结果保持一致,表明该方法可以用作既有普通建筑的雷灾风险评价。
Based on the theory of fuzzy mathematics, AHP is used to establish the set of factors affecting the risk of mine disaster and to determine the weight of each factor. On this basis, the risk assessment of mine disaster is divided into four levels: safety, basic safety, danger and extreme danger, and invited experts in the construction of mine disaster risk assessment and evaluation of each factor to assess and rank, and then calculate each indicator , And realizes the transformation from qualitative analysis to quantitative analysis of mine disaster risk assessment, and establishes a multi-level fuzzy comprehensive evaluation model of mine disaster risk of ordinary buildings. In order to verify the judging effect of the evaluation model, a R & D building in Dongguan was selected to carry out risk assessment of lightning disaster. The evaluation results were compared with those of “Lightning Protection Part 2: Risk Management” (GB / T21714.2-2008) The results are consistent, indicating that the method can be used as an existing ordinary building risk assessment of mine disaster.
