摘要
大藤峡水利枢纽是珠江流域防洪控制性工程。针对大藤峡水利枢纽建设过程中面临围堰拆除难度大的问题,提出了围堰“Z”形水下拆除方案;针对运行期间面临泄水闸调度方式复杂、船闸下游航道连接段通航水流条件变化以及坝前排漂等问题,优化了闸门分区首启原则,提出了填筑透水堤改善船闸下游航道连接段水流条件以及构建自动排漂装置等解决思路。相关研究结果可为解决大藤峡及其他水利枢纽建设及运行期所面临的共性问题提供借鉴。
The Datengxia Gorge Water Conservancy is a flood control project in the the Pearl River basin.In view of the difficulty of cofferdam demolition in the construction of the Datengxia Gorge Water Conservancy,a“Z”shaped underwater demolition scheme of cofferdam is proposed.In order to solve the problems such as complicated sluice dispatching mode,changes of navigable flow condition in the downstream channel connection section of the sluice,and drift in the front of the dam,the principle of sluice zoning first opening is optimized.Some solutions such as filling in permeable dikes to improve the flow condition of the downstream channel connection section of the lock and building automatic drainage and bleaching devices are put forward.The relevant research results can provide reference for solving the common problems in the construction and operation period of the Datengxia Gorge Water Conservancy and other water conservancy projects.
