摘　　要：广利河口拦门沙航道水深较浅,用双导堤结合航道疏浚进行整治。通过潮流定床模型试验对航道走向、导堤间距、高程、水流流态和堤头布置等进行了方案优化,同时采用局部动床定性试验进行了验证。推荐方案沿程流速、流态分布合理,基本能维持航道水深并满足设计船型的航行条件,可供类似河口治理参考。At Guang-li River estuary, the navigation channel is too shallow. Double guard jetties and dredging are used simultaneously to solve the problem. The navigation channel direction, the distance between jetties, the elevation of jetties, the outlet flow state and the layout of jetties are optimized in the fixed bed tidal model test. The local movable-bed test results show that the flow velocity and flow state along the channel of the recommended plan are reasonable and can basically maintain the channel water depth and satisfy the sailing conditions for designed ships.
