摘要
结合嘉陵江苍溪、新政、金溪、凤仪场枢纽等实际工程,通过水工模型试验和船模试验相结合的方法对船闸引航道口门外连接段通航水流条件标准进行了初步探讨。研究结果表明,由于船闸引航道口门外连接段出现回流的几率低,其水流条件主要由纵向流速Vy和横向流速Vx控制,对于山区河流Ⅳ级航道,当连接段布置在主航道一侧时,其水流控制指标Vy≤2.6m/s,Vx≤0.4m/s时,船舶通过连接段进出闸的航行状态均较好。
Based on Cangxi, conditions criteria for connection reac Xinzheng, Ji h of shiplock nxi and Fengyichang projects on Jialing River, navigable flow approach channel on mountainous river is studied by hydraulic model test and ship-model test. Generally, reverse flow rarely exists in the connection reach of shiplock, and longitudinal velocity Vy and transverse velocity Vx are the pacing factors of navigable flow conditions for connection reach. The model test result indicates that when the connection reach is laid on the same side of main channel, the navigable flow conditions criteria are：Vy≤2.6m/s.Vx≤0.4m/s for classlV channel on mountainous river.
