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。To counter the problem of navigation-obstruction under Shaxikou hydropower station due to insufficient water depth on sill and channel in the dry season and the large velocity and disordered flow pattern in the channel,we follow the regulation idea of building dams and open channel combined with reef blasting to adjust the diversion ratio, raise the water level of the shiplock gate and channel during the dry season, adjust the flow state,and improve ship navigation conditions.Adopting the 1∶50 physical model test to study the waterway regulation scheme,and according to the problems existed in the design scheme,we analyze multiple schemes.By the optimized scheme,the water depth on sill and channel,flow velocity and flow pattern satisfy the design requirements.
