摘　　要：赣江新干枢纽-龙头山枢纽两坝间长河段虽为龙头山枢纽库区河段,但仍存在较多的通航安全问题,如局部区域水深不足、先期整治建筑物碍航和桥区通航不畅等。针对上述问题,提出了航槽浚深、丁坝拆除、航路调整等整治方案,并采用长河段二维水流数学模型对该河段Ⅱ级航道整治方案进行试验研究。结果表明:整治方案实施后,航道通航水流条件得到了改善,航道尺度均可达到建设标准。具体表现为:设计航道线内水深均能满足最低通航水深3.8 m要求,航道内横流减小,不良流态消失,航路更加顺直等。Although the long section from the Xingan junction to Longtoushan junction on the Ganjiang River is Longtoushan junction reservoir section, there are still many navigable safety problems, such as insufficient water depth in local area, obstruction of navigation by pre-regulated buildings and poor navigable bridge area. Considering the above problems, we put forward some regulation schemes, such as channel dredging, groin removal and route adjustment, and uses two-dimensional flow mathematical model of long river to conduct experimental research on the regulation scheme of Ⅱ level channel of the river reach. The results show that after the implementation of the regulation scheme, the navigable flow condition of the channel is improved and the channel scale can reach the construction standard. Specifically, the water depth within the designed channel line can meet the minimum navigable water depth of 3.8 m, the cross-current in the channel decreases, the bad flow state disappears, and the route is more straight.
