摘　　要：2016年汛期安徽沿江圩区遭受了重大洪涝灾害,部分堤防段出现了多处跌窝等严重险情,为减轻跌窝造成的堤坝安全运行隐患,在对跌窝险情成因详细分析的基础上,提出了灭杀白蚁和垂直防渗技术综合处理方法,并对枫沙湖堤防进行了跌窝处理优化设计,加固设计需根据圩区堤防跌窝分布、渗漏部位、地质条件、施工条件、造价等实际情况选择方案,应用结果表明该处理方法合理有效,对同类工程具有借鉴意义。In the flood season of 2016,the levee in the riverside polder area in Anhui Province suffered a major flood disaster,and parts of the levee appeared a number of seriously dangerous case.In order to reduce the hidden dangers in safety operation of the dam caused by the collapse sink,based on the detailed cause analysis of the collapse sink,the comprehensive treatment methods of termite extermination and vertical anti-seepage technology were put forward,furthermore,the optimal design and practice for the treatment of the collapse sink were also carried out in Fengsha Lake.The results of the application showed that the treatment method was reasonable and effective,and the reinforcement design should be selected according to the actual situations such as the distribution of the collapse sink,the location of the leakage,the geological conditions,the construction conditions,the cost and so on.This method could be used as a reference for similar projects.
