【摘要】：针对沙溪口水电站坝下河段存在的枯水期船闸门槛水深及航道水深不足、流速大流态紊乱的碍航问题,采取筑坝、新建明渠及炸礁相结合的整治思路,调节左右汊分流比,抬高枯水期船闸出口水位,增加航道水深,调整流态,改善船舶航行条件。采用1∶50正态物理模型对航道整治方案进行试验研究,并根据设计方案存在的问题进行多方案研究分析,优化后方案船闸门槛水深、航道水深、流速及流态满足设计要求。
[Abstract]:In view of the problems of insufficient threshold water depth and channel water depth of shiplock in low water period and disturbance of large flow state of velocity in Shaxikou Hydropower Station, a new regulation idea of combining damming, new open canal and blasting reef is adopted to adjust the ratio of left and right branch diversion. Raising the water level of lock outlet in dry season, increasing channel water depth, adjusting flow state, improving ship navigation condition. The 1:50 normal physical model is used to study the regulation scheme of waterway, and according to the problems existing in the design scheme, the multi-scheme research and analysis are carried out. The optimized scheme meets the design requirements for the threshold depth, channel depth, velocity and flow state of the shiplock.
