摘要
汛期洪水引起的堤防溃口严重威胁当地的农业,交通运输,生态环境及附近居民的生命财产安全,研究堤防溃口的发生机理和抢险堵复新技术,具有极其重要的理论意义和应用价值。结合国内外对堤防溃口的相关研究内容,评述了堤防的类型、堤防溃口的发生因素与发生过程以及堵口技术的研究现状和动向,提出了3点认识与建议:(1)堤坝溃口水力边界特征分析;(2)数值模拟与物理模拟的溃口水流特性研究;(3)堤防溃口水力特征研究的认识与建议。
The levee breaches caused by the flood has posed a serious threat to the local agriculture,transportation,ecological environment and the life-property safety of the nearby residents.It has the extremely important theoretical significance and application value by studyig the occurrence mechanism of dike breaks and the new technology of breaches＇ rescue and repairing.Based on the related researching contents of dike breaches at home and abroad,a brief review of the type of dikes,the occurrence factors and generating process of levee breaches are discussed,three suggestions are put forward： hydraulic boundary feature analysis of dam breaks; numerical and physical simulation of the flow characteristic of the burst and suggestions on the hydraulic characteristics of levee breaches.
