基于改进层次分析法的地下建筑火灾安全评价研究

Study on Fire Safety Assessment of Underground Building Based on Improved Analytic Hierarchy Process

地下建筑由于其密闭性特点,一旦发生火灾往往造成严重的损失。为了更客观地确定影响火灾因素的权重,利用事故树的结构重要度对传统层次分析法进行改进。运用改进的层次分析法对地下建筑火灾的各种危险因素进行分析,分析结果的准确性有所提高。将改进的层次分析法与模糊综合评价相结合应用于某地下建筑火灾危险性评价中,结果表明,改进的层次分析法可用于地下建筑火灾危险性评价中,同时为地下建筑火灾的预防和日常管理提供了科学的依据。

Because of the tightness of the underground building, serious losses is caused once the fire happen. In order to determine the weight of the fire factors more objectively, the structure importance of fault tree is used in analytic hierarchy process. The accuracy of the analysis result is improved by using improve analytic hierarchy process at the risk factors of underground building. The result of assessment is consistent with the fault when improve analytic hierarchy process and fuzzy comprehensive evaluation are used together. The results show that improved analytic hierarchy process can be used in the fire hazard assessment of underground buildings, and provides a scientific basis for the prevention and management of underground fire.
