【摘要】:堰塞湖排險的一個關鍵問題是如何針對實施不同應對措施情況下的堰塞湖潰壩概率進行估計,這是一個值得關注的重要研究課題。本文提出了一種基于故障樹分析(FTA)的堰塞湖潰壩概率估計方法。首先,通過堰塞湖排險問題的實際背景分析,基于FTA構建了堰塞湖潰壩故障樹的基本架構;然后,通過相關領域知識、歷史案例分析、專家主觀判斷和多位專家主觀判斷信息的融合,可以確定實施某一應對措施情形下故障樹中各基本事件在不同時段內發(fā)生的概率;進一步地,依據構建的故障樹和基本事件發(fā)生的概率,給出了在不同時段內堰塞湖潰壩事件發(fā)生的概率的估計方法。最后,通過一個實例分析說明了本文所提出方法的可行性與有效性。
[Abstract]:A key problem is how to lake the lake for risk probability of dam failure to implement different measures under the condition of estimation, this is an important research topic worthy of attention. This paper proposes a method based on fault tree analysis (FTA) of the lake dam break probability estimation method. Firstly, through the actual background of the lake for risk problem analysis of the basic architecture of FTA constructed lake dam break based on fault tree; then, through the relevant domain knowledge, historical case analysis, the integration of expert subjective judgment and experts subjective judgment information, can determine the probability of each basic event of fault tree and the implementation of a response case occurred in different periods; further according to the probability of fault tree construction, and the basic event probability estimation method, the lake in different period of dam failure events are given. Finally, through a Example analysis shows the feasibility and effectiveness of the proposed method.

【正文快照】: 0引言堰塞湖通常是指,在一定的地質與地貌條件下,由地震、強降雨或火山噴發(fā)等突發(fā)事件引發(fā)的滑坡體、泥石流、火山噴發(fā)物、冰川堆積物等物質橫向阻塞河道形成壩體,進而造成上游段壅水而形成的湖泊[1,2]。堰塞湖壩體主要是由巖土快速堆積而成,壩體結構松垮、組成物質松散,且與,
