黄河下游堤防失事模式及识别方法

Yellow River Downstream Dike Failure Mode and Recognition Methods

重点针对黄河下游堤防工程漫决、冲决、溃决失事破坏,通过分析影响黄河下游堤防安全的主要因素,构建了黄河下游堤防工程失事模式,提出了基于模糊贴近度和投影寻踪的溃堤模式识别方法,据此构造了黄河下游堤防主要溃堤路径,为黄河下游堤防隐患险点先后处理及采取相应工程措施等决策提供依据。

Considering with main factors to the security of the Yellow River dike,the failure mode had been constructed combined with major prob-lems existed in the dike project. Furthermore,the recognition method of dike failure had been proposed based on fuzzy nearness and projection pur-suit. The application of the failure mode and path were helpful to the current safety demonstration of the dike with the security hidden trouble. On the basis,the decision-making of treatment on the hidden trouble in the lower Yellow River dike could be taken successively according to the fail-ure paths.
