考虑城市公园特征的地震应急避难场所安全评价研究

Research on Safety Evaluation of Earthquake Emergency Shelters Considering the Characteristics of Urban Parks

为了合理评价城市地震应急避难场所是否能够满足安全标准,有效提升地震应急避难场所的建设、管理水平,从安全性角度出发,综合运用层次分析法、德尔菲法、综合指标法,建立了考虑公园类型的地震应急避难场所的安全评价方法,并以某地震频发城市的公园避难场所为研究对象进行应用验证。评价结果表明:某公园地震应急避难场所的安全性属于B等级,工作状态属于“良好”状态,但在安全性上应该“适当加强”。

In order to reasonably evaluate whether urban emergency shelters can meet safety standards and effectively improve the construction and management level of emergency shelters,the analytic hierarchy process,Delphi method,and comprehensive index method were comprehensively used to establish a safety evaluation method of earthquake emergency shelter considering park type in the view of the perspective of safety,which was verified by taking the park shelters in an earthquake-prone city as the research object.The evaluation results show that the safety of the emergency shelter in one park belongs to the grade B,and the working condition is in a“good”state.Simultaneously,the safety should be“appropriately strengthened”.
