基于模糊聚类分析法的震损水库除险加固顺序研究

Study on Danger Control and Reinforcement Sequence of Earthquake-damaged Reservoir Based on Fuzzy Clustering

针对震损水库等级划分涉及因素多、综合评判边界模糊等问题,基于对震损水库实际情况的分析,采用模糊聚类分析方法,提出震损水库除险加固顺序模型。以汶川地震后江油市震损水库为例,对震后水库的受损程度进行定量化的综合分析,以确定水库受损级别,并针对评价指标的强弱拟定科学的加固顺序,对防止地震次生灾害的发生具有重要意义。

Aiming at the problems of multiple factors and fuzzy boundaries in the classification of damage reservoirs, based on the analysis of the actual situation of earthquake damaged reservoirs, a reinforcement sequence model of earthquake damaged reservoirs was put forward by using fuzzy clustering analysis method. Taking the earthquake damaged reservoir in Jiangyou city as an example, a comprehensive analysis was carried out about the damage degree of the reservoirs, and the damage level of the reservoir was determined. Furthermore, the reasonable reinforcement sequence was given. The research is important significance to prevent the occurrence of secondary disasters of earthquake.
