摘要: 为满足航运和经济发展要求,大源渡枢纽拟在一线船闸的基础上扩建二线船闸,现有的一线船闸上游引航道口门区位于弯曲河段,水流条件比较复杂。为使扩建后的二线船闸上游引航道口门区水流条件能够满足规范要求,主要选取3种不同形式的隔水墙布置方案,在最大通航流量Q=17 500 m3/s(10 a一遇)下,研究不同的隔水墙布置方案时上游引航道口门区通航水流条件、枢纽河段行洪能力以及其改善措施。结果表明:隔水墙能够改善口门区水流条件;综合考虑通航和行洪的要求,上游引航道选取透空式隔水墙布置方案较为合适。其研究结果可为类似工程的设计研究提供参考。

Abstract: To meet the requirements of shipping and economic development, a second shiplock is planned to be built at Dayuandu Navigation-Hydropower Junction, but the approach channel’s entrance area in the upstream of the existing first shiplock is in bend reach with complex flow conditions. To make sure that the flow condition at the second shiplock could meet standard requirements, we designed three cases of cut-off wall pattern, and analyzed the navigation condition, flood discharge capacity and improvement measures under maximum flow (Q=17 500 m3/s, once in 10 years) respectively in the presence of these three cut-off walls. According to calculation results and comprehensive considerations, we recommend permeable cut-off wall at upstream entrance area of approach channel. The research result could be regarded as reference for similar engineering design.
